TL/DR I made a video review here - https://aicopy.org/review-10web-io-and-why-its-powerful-ai-could-be-the-best-purchase-you-make-this-year/

I was hesitant to trying 10web, due to the negative review - and little uptake. But, I tried it, and...

I was shocked and surprised.

Simply put, it is awesome. The ai feature alone will save me hours from client requests, sourcing fonts, colours, spacing etc - it allows me to take a site a client likes, and hit the ground running.
What's better is it is Elementor, so all of my original plugins still work as normal.
It has optimisations and backups ready to go - and if you do opt for hosting (i didn't) it comes at a reasonable price.
Do not get this expecting a ready-made sight - but it does give you a massive head start and the road map with online stores looks very promising.
