Best NFL: Minnesota Vikings
Yes I'm a homer, but it is I think one of the best logos in the sport. However I do prefer the Viking horn on the helmet, however I don't consider that the logo.
Non Homer NFL: Oakland Raiders
This would have to be my favorite logo that isn't the Vikes. I actually like the whole Raiders scheme of things with the black and silver and I love their jerseys. It's not fierce, it isn't angry, but it is old school.
MLB: Philadelphia Phillies
Yup another homer pick. I love everything about the Phillies logo, the P, the diamond with Phillies across, everything.
Non Homer MLB: Chicago White Sox
Love the ChiSox logo. I think it is the font style, it just looks cool and can't go wrong with the easy going black and white color scheme.
NHL: Minnesota Wild
Interesting pick if I must say so. I just dig the color scheme and the whole "wild" setting with the forest inside that of the bear or whatever it is.
NBA: Dallas Mavericks
I love this logo. The color scheme, the horse, the font, the basketball in the background, everything.
Least favorites
NFL: Miami Dolphins
I just don't like this logo. I find it cartoony and cheesy. Not a fan of the color scheme nor the dolphin with the helmet and such.
MLB: Arizona Diamondbacks
Thank god they updated this. While I'm a fan of purple, this didn't work for them. The whole teal, purple, and gold just doesn't work. Plus the snake looks cartoony and I find myself chuckling at it.
NHL: Vancouver Canucks
Sorry TM. While I like that they change the color scheme for the newer version, I still am not fond of it. I prefer the older one much to this one. The whole dark red, dark blue, and silver just didn't work for me. While I'm not fond of the green and blue, I do enjoy the alternate logo with them.
NBA: Milwaukee Bucks
I didn't think they could make the green and purple style worse, but they almost succeeded with this. The color scheme is terrible, I hate the font, and I just don't like the Buck at all. Doesn't make me fear the deer.
