Not which is the best but which is your favorite/the one you would want to fight with? Overeem or Cain or prime Fedor? DC or Rumble or prime Shogun? Rockhold or Romero or prime Anderson? Wonderboy or Woodley or prime GSP? Alvarez or Pettis or prime BJ? Conor or Aldo or Frankie? Cruz or Dillashaw or prime Faber? Nunes or Shevchenko or Ronda? Not going to do FLW or WSW since those would probably be really one-sided lol.
