Of course there are things that I would change, but I'd say that overall I've enjoyed my time with both for different reasons.
When I'm in the mood for a traditional 5e D&D dungeon-diving experience, I play Solasta.
When I'm in the mood for a narrative-driven character-centric experience, I play BG3.
They're similar, so it's expected that comparisons would be drawn between them, but they're different enough to fill two distinct niches for me.

I don't want to fall to bits 'cos of excess existential thought.
