User blog comment:RoznosicielCiast/Darius is NOT the most powerful champion in League. Which champs are stronger than him in your opinion?/@comment-76.93.211.214-20130123023852/@comment-76.93.211.214-20130123024440

Aside from that, Darius, Cho'Gath and Garen are all champions that can build relatively tanky (or end up tanky in Cho's case) and still deal fair amounts of damage and provide to teamfights. Garen probably has the least counters right now, since slow kiting is hard because of Decisive Strike. If you can successfully gank Darius a LOT (I mean practically camping top lane) early on, he can't do much at all. Same goes for Cho, as both Darius and Cho'Gath have no true escape moves, only CC.

However, tower dive any one of these three 1v1 and you will most likely die unless you have a skill that makes you untargetable (ex. Fizz pole, Vlad pool, Fiora ultimate).
