I generally like seeing fighters who shows up in the ring like a true fighter that he is and gives everything he's got to finish it.
I generally dislike fighters who has no killer instinct in capitalizing on their opponents, just showing up in the ring to display their superiority only. It makes it look boring to watch.
Though sometimes, my less likable fighters does the former while my likable fighters sometimes does the latter so I can't throw up some list just to love/hate on them
They're in the ring to perform whether good or bad nonetheless. Peace
