I've tried similar briefs from other companies but, while they are all great products, I like these the best.

First, the butt on these briefs is 3/4 coverage rather than full coverage. Second, these briefs seem to be cut a bit higher so as to be worn closer to the wast, rather than at the hips. Not only do I find that more comfortable, but it seems to keep them from sliding down, which is a problem with some of the competitors.

As for sizing, if you follow the company's guidance they fit perfectly.
