A chance to post that meme I made!
"Let me put it to you this way, Tav. You can buy better games than Solasta, but I like Solasta. Yes, it has a linear story, and the voice acting is rather stiff, and you can't multiclass, but–it's brilliant!"
I don't actually know that I would say BG3's story is undeniably better. It's more polished, sure, and it's more open-ended, but that doesn't necessarily make it better. Granted I'm not done with it yet so I can't say for sure, but I really like Solasta's story, especially the second campaign.
I think there's also something to be said about having four fully voiced player-made protagonists instead of one silent protagonist and a ton of NPC companions. There are scenes made up entirely of your party talking to each other. Which like, yeah, BG3 has that too, but Astarion and Shadowheart aren't mine. Nora and Crag were. The writing isn't as tight, the voice acting is relatively amateurish, but I like it.
