I love wrestling, but MMA has my money right now. I can fully understand why some would call some fights boring. When you have 2 fighters who let's say are skilled on the ground with whatever grappling discipline is their base, and they put on a grappling clinic. To the uninitiated, I can see where it would be considered boring. If you have an understanding of transitions, submission attempts, getting out of submissions, etc it can be very exciting. Add in the element of the standup game where flash knockouts occur, and you have the fastest growing sport in terms of popularity going right now. Wrestling is all about pageantry. The show. The talents are still extremely athletic, but at times, we as fans, can get bored or feel as if our intelligence has been insulted by a storyline. You don't have this in MMA.
It really is a matter of preference. With wrestling, I have lost a lot of interest, but with MMA, it has garnered my attention. With 10 years of amateur wrestling, I enjoy seeing guys I grew up idolizing, making money and becoming something more than just a wrestler. Pro wrestling will never die. It's too big and too strong, with too large of a fanbase, while MMA is still growing. I think when it comes to the heart of it, you're comparing apples to oranges. I give my nod to MMA.
