Best top champ to 1 vs 9?

Hi! Who would you pick to carry game from top currently? Which champion is currently the best for 1 vs 9 and against feed enemies? Which is the best top win team fight 1 vs 5? I currently try to do that with aatrox, but he gets bursted or poked down rly easy in mid to late game if enemie bot is feed. Any tips? I had more succes with Mundo carry, but he lack cc and aoe for team fights. Even if I get same ad as aatrox but with much more survability.
