Solasta's and Pathfinder's target audience is a much narrower one than BG3. They can still be successful with a smaller target audience because they also have a smaller budget.
For myself I am only currently interested in BG3 of the 3. From what I have read Solasta has weak characters and story, and choices don't impact the story. Pathfinder's characters look interesting, but it lacks cinematic dialogue, which is important to me, and also has harsh resting penalties, which is a big negative to me.
