I am migrating my half-made sites from Elementor to Beaver Builder because of more technical reasons and reputation. Beaver Builder is more developer-friendly, a GPL plugin, and have a healthy community.
I have high knowledge in CSS and HTML, so i don’t need features rich page-builder. More like vanilla users 
Day 001:
I just used Beaver Builder this morning to build my website, which has quite a complex design layout. I admitted I had to rework some CSS rules on my custom Genesis Framework theme. The experience is tricky at first because there’s some CSS conflicting with bootstraps.
I also had to work with many CSS writings to suit my visual mockup. However I liked the fact, the builder is snappy and sleek, by this I meant. What I build on back-end is what I get. 100% correct, it’s also very responsive. With Elementor I had to set and customize each row. Probably because Beaver Builder using Flexbox for the column systems?
My suggestions as following:
- Add Justify Features.
- Allow Custom Width for columns or modules.
So Beaver Builder already has a solid foundation, but please do add few functions and features that is essential. ( In this case, doable by simple CSS, but no one like writing a lot of CSS. )
I will update, my experience each days
