Have you seen AAA? It's a madhouse.
Certainly loud and passionate fans, but in our polite Canadian way. About as similar a product as there could be to American wrestling with maybe a smidgeon more diversity.
Agreed on AAA, seems to me they have always had a more American style than their CMLL counterparts, especially with the influence of Konan in their booking office. But it is even more chaotic and hard to keep up with. They change storyines, heels, and faces like we do shirts.
The UK always seemed like more of a hybrid to me, although I have not been able to watch a whole lot of it. Seemed like their shows were like the AWA with technical wrestlers pushed to the top against monster heels. Heavy rulebreaker vs athelete kind of thing, very blue collar.
Mexico has always been more about color, stlye and show. Larger than life has always been the norm. It is obviously a more energetic acrobatic style. Everything down to their elaborate ring entrances (which have blown everyone elses ring entrances away since the 80's) is heavy on the spectacle. A departure from the everyday life.
In Japan fans do apperciate the opera that is the match psychology and apporve realism. They will clap more for a well executed move than for a hot tag. However there is a large portion of their fanbase that was enamoured with large rough housing Americans. Japan to me has always been the most accepting of other cultures and love to blend other styles in with theirs.
Agreed with the previous poster on Canada.
You could also examine the different cultures within the US. Each territory had its own unique culture back in the day.
The Northeastern style promoted heavily to cater to it's multi-ethnic fans. They used ethnic rivalries to promote much like boxing did in the 20's-60's. A major reason for this was that in the northeast the boxing and wrestling offices were controlled by the same men. Their champs like Bruno, Pedro, and Antonio, represented specific ethnic groups and rallied large ethnic fan bases. That was until the cable boom of the 80's when it became the world's media hub and promoted a national, even global style to match the booming media center the northeast had become.
The Mid-Western style like the WWA, St. Louis, and AWA, was a very grappling based style to fit the blue collar fan base. In ring technical skilled faces like Verne Gagne and gifted heels like Harly Race and Nick Bockwinkel battled, with an added does of barrel chested blue collar brawlers like Dick the Bruiser the Crusher, and Mad Dog Vachon, who were sprinkled into cards to add more personality.
In the turbulent South, chaos and storylines reigned supreme, as in CWA (Memphis), World Class, Contenintal, Florida, and Georgia. Most of these companies promoted heavily with tag teams early in their histories. A heavy rotation of traveling heels battled long time stationary faces who were not afraid to break the rules to put down the outsiders, like the Von Erichs, Lawler, Bob Arstrong, and Dusty Rhodes, who represented the fans becuase they considered them local. Oftentimes family was a common theme within these companies. This fit the Southern family vs the rest of the world mentality many southerners have.
Mid-Atlantic was a little different and seemed to thrive on the chaos, tag teams (Hawk and Hansen, The Andersons), and stationary faces (Johnny Weaver) like that of a Southern promotion but lauding the technical prowress of their top stars like Ric Flair, and Ric Steamboat just like a Mid Western promotion.
Out West, especially in the Cali WWA, the line between heel and face was always blurred, different cultures were promoted (much like the Northeast) it matched the come and go mentality of the area. There was also an influence of the lucha high flying style that fit the flamboyance of the area.
However the Pacific Northwest always seemed like the exception to me, as it seemed like more of a classic southern territory.
