Let's be real, BG3 is a far far far far far better game than Solasta.
BG3 has a bigger budget, better graphics, better story and so on.
But regarding game mechanics (especially using the DnD rules in combat) and user interface Solasta is miles ahead.
I´d rather have several pop ups for reactions than not having full control over what my chars are doing.
And the ready action is often good when you cannot reach the enemy on your turn.
