Solasta's devs are 17. Stay focus, the comparison between the games is usualy related to combats.
BG3 is more beautifull, has a more interresting and depth story, better animation and visual effects, the full D&D5 licence for classes and subclasses, the FR etc... But combats in Solasta are way more D&D and strategic.
(And Solasta's UI is better, both for newcomers and old players + you have a better feeling of D&D campaign than in BG3)
