Nova Uniao fighters don't really have creative striking, they're pretty straight forward MT fighters, just very, very good at it.
I would definitely prefer Nova Uniao fighters over any American wrestlers, though. Nova Uniao MT/BJJ fighters are far more exciting to watch than any American wrestler who prefers to take guys down and control them or put them against the fence and control them.
Other than that, the most enjoyable for me is to watch guys who mostly use their hands and like to use volume and body shots. Also when they have great movement, so TJ has always been a pleasure for me to watch for quite a few years now. I'll take that kind of fighter over a straight MT guy any day. TJ may be a 'bang MT' fighter, but his hands are the biggest weapon besides his left switch kick to the head. I could really go on all day about what kind of fighters I like, but meh, too long and nobody likes a long ass post, this is already long enough for you lazy mofos!
