I started with the hanes and frankly except for the price point I don't like them so much. Either Michael Jordan has special made ones or he is just making a buck cause I don't get it.
I prefer Jockey Pouch Boxer-Briefs myself, been wearing them for years now. FTL also makes a PBB, and I like those also but not as much, and I think some of the other hi-end brands make the PBB.
As an FYI, I am no shower, and don't hang like the "avg LPSG guy" so...?
Best way to know for sure is to find a sale, experiment with the brands and find the ones that are comfortable for you. That's how I found my Jockey's.
Good Luck.
