I'm not throwing shade at BG3; I've also enjoyed it, but something about the sheer amount of options and more widely diverging story paths in Wrath just does it more for me. I also like the art style more, but that's strictly subjective and I accept that.
To a lesser and more personal extent, I despise Wizards of the Coast/Hasbro and their recurring attempts to monopolize and bully third party game developers and players alike and I don't like to even indirectly trickle money their way compared to Paizo. Yes yes, no ethical consumption and all that, but Paizo's way less fucked up with both distributing game materials and open licensing agreements.

That's all I had to say. If you've already finished BG3 or it wasn't quite to your liking and you'd like an alternative, give Wrath a try. 
Not played BG3 yet but played wotr.
WOTR is genuinely a great game. Far better than Kingmaker and feels like a true successor to old Baldurs gate.
The Mythic Paths really make it great. You can have so many unique playthroughs with that.
Hate the Crusade management though which is necessary to explore the map quickly.

The fact that the game straight up lets you just be a lich even tho all your party members leave and then there’s back ups to continue the game is so cool lolI mostly agree, but I liked the kingdom management in Kingmaker. Juggling your different advisors and being forced to make hard choices was fun
