There is a third route that is almost always missing from page builder comparisons: keeping the block editor and extending it instead of replacing it with a page builder.
That is exactly what Spectra, Kadence Blocks and GenerateBlocks do. They bring containers, grids, buttons, accordions and the like as real WordPress blocks — you carry on working in the familiar editor, just with considerably more building blocks.
For a substantial share of the websites I see, that is the more fitting answer than a page builder. And for another share it is not.
The short answer
Block plugins, if your website consists essentially of content — text, images, a few designed sections — and you want to keep it lean.
Elementor, if you go into detail in design terms, need popups and forms, or want to build headers, footers and post templates freely.
What these plugins actually are
The WordPress block editor has become good, but out of the box it lacks the design building blocks you need on a company website: a decent container with a background, a column grid that wraps sensibly on a phone, a button that looks like something.
The three candidates fill exactly that gap:
Spectra (from the makers of Astra) is the most extensive of the three — many ready-made blocks plus a library of complete page templates. Closest to what you would expect from a page builder.
Kadence Blocks is the balanced middle road: very good containers, a well-thought-out row and column system, usable forms. Works particularly well together with the Kadence theme.
GenerateBlocks is the opposite of extensive — four or five building blocks, no more. That is precisely the idea: minimal blocks, maximum control, practically no ballast. Best used together with GeneratePress.
On the corresponding themes: GeneratePress vs. Astra vs. Kadence.
At a glance
| Elementor | Spectra | Kadence Blocks | GenerateBlocks | |
|---|---|---|---|---|
| Basis | its own editor | block editor | block editor | block editor |
| Feature range | very high | high | moderate | deliberately minimal |
| CSS delivered | the most | moderate | low | very low |
| Templates | very many | many | some | none |
| Forms | in Pro | basic | yes | no |
| Popups | in Pro | no | no | no |
| Theme Builder | in Pro | via Astra Pro | via Kadence Pro | via GeneratePress Pro |
| Learning curve | gentle | gentle | gentle | gentle, but design knowledge needed |
| Dependency | high | moderate | moderate | low |
Where the block plugins score
You stay on the WordPress standard. Your content sits in WordPress as real blocks, not in a vendor's own format. If you switch the plugin off in five years, your text and images remain as orderly HTML. With Elementor the page is empty at that point. That is the most important difference, and it is almost always overlooked.
Considerably less ballast. GenerateBlocks in particular delivers only the CSS actually needed on the page in question. Elementor brings a base stock that always comes along.
You are on the side of development. WordPress itself develops the block editor further — full site editing, style variations, everything new arrives there. Page builders have to run after that development or deliberately stand beside it.
Lower costs. All three have usable free versions, and the Pro variants are cheaper than Elementor Pro.
Where Elementor scores
Fine design work. If you want a section exactly the way you picture it — spacing, overlaps, background shapes, motion — you get there faster with Elementor. The block plugins give you building blocks; Elementor gives you adjusting screws.
Popups and forms. No block plugin has a popup system that can keep up with Elementor Pro. And for forms with conditional logic and integrations you are better served with Elementor or a dedicated forms plugin.
Theme Builder from one source. Headers, footers, post templates, archive pages — with Elementor Pro you build that in the same tool. With the block plugins you need the Pro version of the respective theme, and you then work in two systems.
Templates and ecosystem. Anyone who does not want to start from zero will find something ready-made in Elementor for practically any purpose.

Which of the three, if any?
Spectra, if you are coming from a page builder and want the transition to be as soft as possible. It feels closest to what you know.
Kadence Blocks, if you want a balanced solution and work with the Kadence theme. For most company websites that is the most practical of the three.
GenerateBlocks, if you know how a layout should be built and want maximum leanness. It hands you very little — for someone with a design instinct that is an advantage, for others a hurdle.
The honest comparison of loading time
Yes, the block plugins deliver leaner pages, GenerateBlocks most clearly. That is measurable and it is not marketing.
And as with all builder comparisons: it is rarely the reason a website is slow. Uncompressed images, cheap hosting, missing caching and a dozen third-party scripts weigh more heavily. A well-maintained Elementor site beats a carelessly built GenerateBlocks site.
What actually works is set out in WordPress Page Speed 2026 and Optimising Elementor performance.
Switching
There is no automatic transfer from Elementor to a block plugin — you rebuild the pages. The effort is the same as with any builder switch.
But there is a route that works well in practice: convert step by step. You build new pages with blocks and leave existing ones in Elementor until you revise them anyway. After a year the important part is converted. Because both run in the same WordPress, that causes no trouble.
The reverse route is easier, incidentally: anyone moving from blocks to Elementor has clean HTML as a starting point.
My recommendation by situation
Block plugins, if your website consists essentially of content, if you want to keep it lean, if you want to stay on the WordPress standard long term, and if you can do without popups and complex forms.
Elementor, if you go into detail in design terms, if you need popups, forms with logic or freely built headers and footers, if you depend on templates, and if you value German-language instructions for every step.
Both, during the transition. That is permitted and it works.
Frequently asked questions
Can I use several block plugins at the same time?
Technically yes, sensibly no. You take on duplicate building blocks and competing styles. Settle on one.
Do block plugins replace Elementor completely?
For content-driven websites largely yes. For designed landing pages with popups, form logic and elaborate sections, no.
What about the block editor on its own, without an additional plugin?
For blogs and text pages it is now enough. As soon as you need designed sections it becomes laborious. The detailed comparison is in Block editor versus page builder.
Are the free versions usable?
With all three, yes, and noticeably more so than you would expect. You can try the route without paying anything.
In closing
The question "Elementor or a block plugin" is at heart the question of whether you run a designed website or a content website.
If you have to think about it, it is usually a content one — and then you are leaner, cheaper and more independent in the long run with the block editor plus one of the three plugins.
