Tried TDE once, that resolution system is awful.

I think the wonkiest dice I've ever played with for this would be Eclipse Phase. It's a "d100 under skill" system, but uses the number you rolled as degree of success. So it's like blackjack; rolling high is better, as long as you don't bust. That difficulty modifier can turn a roll from amazing to awful. It's not bad, and it's never caused confusion, it's just funny.
