IMO, Boston Bhangra is currently holds the thrown as the King of comps.... Not only is the whole experience just next level, but the lineup always has a great mix of top teams from all over the continent.
Bhangra Idols also seems like an insanely awesome time but the location is so isolated from other bhangra-power-house cities that it becomes difficult for the lineup to be geographically mixed. Bruin Bhangra may also be in the same boat- the lineup needs some Toronto love to make it complete haha.
Elite 8 was great the first year but from what I've been hearing from a lot of teams lately, it hasn't established itself as the "competition that everyone wants to get into"... The hype seems to have been pretty short-lived.
Also, Bayside Bhangra seems to be the next desired destination for a hell lotta teams.
And finally... PAO BHANGRA
... although it's an exhibition, it's simply amazing.
