Depends on what you are looking for in the champ. They are completely different characters.Killmonger's special ability is true strike imho. But this is mostly needed in AW. in story quests, event quests and alliance quests true strike doesn't play that much of a roleBlade's utility, if you have the trinity, can't be underrated and it makes him an extremely versatile champ.The only other ability he gets from awakening is his regen, which of course is great, but not necessary to clear most of the content in the game. Blade's damage output is crazy when his danger sense is active. I used to underestimate him but right now I take back all the bad things I said about people who praised him by this I'm not saying Killmonger is a bad champ, but if I were to rank up one of them, I'd start with Blade. Killmonger can wait.
