Mine has to be

TNA
NOAH (only for Kenta Kobashi mind)
ROH
NJPW
AJPW

Notice no WWE, the reason for that is i dont count them as a wrestling fedaration anymore as they are more of a talk show with short fights (2 hours show 3 matches FFS)

Difficult to say, i'll just name my fav's and give a small explanation.

TNA - Good solid wrestling, i used to watch both TNA and WWE but i gave up on WWE cause i couldn't stand it anymore.

FMW - gone but damn i liked what i saw. (one day Hayabusa will fly again!)

Old ECW - I really liked the old ECW, or should i say "The Real ECW"
in a way TNA kinda reminds me of ECW fused with the good parts of WCW.

WCW - I might not have seen as much as you Americans but i enjoyed it, though i preferred the 93-98 WCW.

MLW - I liked it until they went from an ECW clone to a ROH clone.
