I guess I have different body proportions from most others because for me at-waist briefs are too high and I need to fold the waistband over to be just right.  That works but it's a little cludgy and wastes time (pun intended) in the bathroom.

These Low Rose Trunks were the solution for me.  It sits at the waist, its soft, and the legs are not too long.  They breathe well in hot humid weather and they don't bind when exercising.  I know they're expensive, but I expect them to last a lot longer than cotton briefs that lose their stretch and get thin after awhile.  I bought as many pairs as my budget allowed and wish I could replace my whole underwear drawer with these.  They're also cheaper on Amazon than any B&M store I saw them at even on sale.  In fact the ones I ordered still had the retail price sticker of $24.
