I would have to agree with you for sure. I am a fan of both sports, but much more of a Boxing fan.
Still, since I am a fan of both sports, and have been watching them for years now, I feel like I can give a neutral opionion on questions like this. Boxing and MMA both produce entertaining, exciting, and great fights. However, if you look at the fight of the year winners over the last few years (or just fights in general), for both MMA and Boxing, the Boxing fights are without a doubt much more entertaining and thrilling.
I don't think MMA sucks, or that it is boring. But when you compare MMA fights to Boxing fights, the MMA fights aren't on the same level in terms of entertainment and suspense.
