General setting guidance

Hello fellow world conquerors,

I just want to start off by saying I absolutely love this game, I started 3,4 years ago and I just go in and out of phases of being obsessed with this game. i enjoy a lot of strategy games like civ5,6,7, red alert, mount & blade, age of empires. And this game is up there for me even though it’s just a mobile game. I love the strategy part of this game, but I never cared enough to dive DEEP into the state to maximize my generals. As I’m beginning to gather elite forces, I figured I’d learn more about it.

I knew from a while ago, Guderian was considered the best general, and the rumor capability was OP, now with the updates and elite forces I’m still trying to learn more about it. From what I’ve read, Manstein is the strongest now paired with the elite tank? What’s the OP setting for manstein? how do I know what tank to pair with which general, and what ribbons/skills should I give my generals? I’ve attached my generals list, lmk what you think.
