Striking is more beautiful to watch even to me. Originally, I was not a MMA fan. I was a kickboxing fan. Kickboxing and boxing is what I trained, and that is what I wanted to watch. I thought the wrestling and grappling shit was boring. In the 90s K-1 was popular in the US, so I watched it all the time. I watched a little bit of PRIDE and UFC, because there were a few prominent strikers in it at the time. Now, K-1 isn't popular at all in the US, so it's hard to watch it. I have to rely on replays online almost always. MMA is now extremely popular, and the UFC is considered a mainstream sport. I still mainly enjoy watching strikers, but having followed and trained some, I am much more educated on all aspects of MMA now that I can enjoy grappling, striking, and other things.
The concussive head damage has been studied in MMA and boxing by doctors. MMA fighters on average have less damage. Now, over long periods of time, there will be athletes from both sports that are punch drunk when they are older, just probably more boxers than MMA fighters.
