Alright, I've never actually watched a full japanese wrestling show and that's mostly 'cause I don't have a clue where to find these, and not sure if I would enjoy segments (if there are any) 'cause I'm gonna go a limb and say it probably isn't english lol, in saying that, the japanese wrestling I've seen on youtube with various moves I've been checking out and everything, I'd have to say their style and the moves they do are so much better and cleaner than what I see on WWE, WWE don't contract wrestlers, they contract entertainers (sure, they did actually train, but regardless, there'd be no place for most of them without WWE, went downhill with the departures of HHH, Ric Flair, Shawn Michaels, Edge, and the late, great Eddie Guerrero, I'm gonna go ahead and put Kurt Angle in that list as well).
The only two promotions I've ever watched is WWF/WWE and TNA... But based on actual in ring ability and moves, which I find more entertaining than the segments, I'd pick any of the great lucha libre feds and indy circuits that don't censor moves like WWE does, one of the guys that I remember seeing on youtube... Great in ring performer, never seen anyone better (then again I haven't seen much), his name's Ricochet, don't know if anyone's heard of him but he is so good in the ring (performs the Double Rotation Moonsault in Sin Gambit's bio)
Here's a fan made vid of his top 40 moves... Love the top 16, and I also love the sell of that Reverse Frankensteiner
Overall, I barely ever watch WWE anymore, except for the extreme or big ppv's (screw summerslam, I only watch HIAC, EC, RR and WM and never live). TNA... I think it was good before Hulk Hogan shows up... He'll eventually be the death of that show.
