First and foremost, for the past two years WWE has technically become the number 1 promotion in Mexico if you look at attendance and tv ratings.
As for the home based promotion, AAA is number 1 by far and has destroy CMLL in tv ratings since the 90's especially this year. CMLL is doing an average of 2.8-3.0 while AAA is averaging over 6.0. They both aired on the same station,same day,right behind each other.
CMLL is better to go to for the live experience, as a television product THEY SUCK. AAA is easier to get into, they used US pro wrestling formats like the one pinfall.
Both companies have weekly shows that usually build up to a major event that comes on regular tv. AAA Triplemania is the only show that airs on ppv. All the other major events comes on free television.
