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. 
Sadly, it isn't co-op multiplayer.
The battles are real-time-ish, but can be paused at any time to give more elaborate commands.
Just so you know, you can switch from real-time-with-pause combat to turn based at any time. Slows battles down, but allows for proper micromanagement of actions.
Aww bummer. If anyone reads this and knows another turn based rpg we can hotseat, which might scratch the same itch, let me know.
I wish I could say otherwise; Wrath is a very good game but I'd be lying if I said it had co-op.
If you haven't already played Larians other game, Divinity: Original Sin, that's worth looking at.
For The King is more digital board game than RPG I guess, but it's still a couch co-op turn-based RPG that's pretty fun
