it's really difficult to say, everyone's going to be a bit biased. i personally say the red wings, simply because that's my favorite team, and and i know even with the terrible economy here in detroit, everyone i know is still 110% for the red wings, even if that means having to sit at home to watch the games on tv. not to mention, especially with a lot of people moving out of michigan and to other states for jobs, red wings fans are starting to spread out, so no matter where the red wings go, there will always be fans in those stadiums.
the blackhawks have pretty good fans too, i went to my first blackhawks game on sunday because my boyfriend is a fan of theirs, but in my opinion (and it's just my opinion, i don't know for a fact), it seems to me like they're completely milking it because they won a stanley cup. not that they shouldn't, they should definitely be excited for that, anyone would, but it seems like they're way too cocky. i've had multiple blackhawks fans rub it in my face, which i find hilarious. they're more like cocky fans than loyal fans - bandwagon fans i guess. but once again, that's completely an opinion.
