To me the feeling was nearly the same with any brand of condoms. I'd suggest whatever fits him the best is the best condom. Different condoms vary in their length and width. And although they're supposed to stretch, even the 1-5 mm variation makes a difference. And anything torpedo shaped
is good. (note that that site isn't very detailed, just to give you an idea)
We ended up liking the Trojan ribbed with the Ecstasy lube. I realize I've mostly been talking about him and not me, but him being uncomfortable kills the mood for me.
