I train BJJ and really enjoy it and also really like watching sport BJJ also, a lot of mma fans would not though. I don't really have much interest in watching wrestling though. The aim of BJJ is to finish the fight a get a sub. Wrestling the aim in to pin the person and control them. I think BJJ can be a bit more flashy and pleasing on the eye so that is why people may prefer it.
