In this whole discussion of Solo-Elementor i find it very odd that the word 'woocommerce' hasn't fallen yet. Mainly WooCommerce and it's ecosystem is the main glue still between WordPress and Elementor. A Sass model could work, but with e-commerce... not easy i think.

I can only tell these are bizar times to build 'paid' websites; wether not knowing if you really deliver durable work.
Besides that: bumping on Elementor that it is bloated is just karma. As the Block Editor and the next Block Pagebuilder will struggle with the same issues. Not speaking of the Block Directory which only could add up more bloat on a faster pace.

The new 'Block'-way of building pages won't be directly coming from core (or Gutenberg) i expect. That will always stay too basic for what the majority of the non-tech users really want to achieve. It's just waiting on the next Elementor for Blocks.

And in preparation for a talk on WordCamp Antwerp (BE) i've tested around 10 Block Pagebuilders. Only one really jumped out for me: Qubely. And from what i've seen: Qubely could be the next Elementor.

Why? Besides the nice UX of settings; they did an amazing job of importing templates and sites. And it's exactly that aspect that users want; and where Beaver Builder created their first fame.
