Your first paragraph makes no sense. By your definition, the bad boxing match would not have vicious shots or good movement whereas the best MMA fight would. Therefore, the MMA fight would be more enjoyable to you.
Secondly, if every MMA fight you've watched has been "roll around on the ground and hope to God that the other person taps out" then you must not have watched very many fights. But you do have limited time and limited money, so to each his own.
