For me, it's adjustable stick tension.

I'd love the ability to quickly fine-tune stick resistance depending on the game.

Personally, I'd rather see features like that than higher polling rates past 1000Hz. To be honest, I don't really notice much of a difference between 250Hz, 1000Hz, or even 8000Hz in actual gameplay, but maybe that's just me.

What's the one feature that would make you upgrade immediately?
