As someone who has used both for an extensive period, I would say they both have their pros and cons. The rolls is stiff since its plastic shell and will never change shape for you, so if its not comfy for you initially don't expect it to mold. It can take a serious beating, scuffing, rain and it won't be hurt as bad as the brooks. My biggest complaint with the brooks was that it wasn't stiff enough and eventually the saddle developed a ridge. Touring on the b-17, I noticed it was getting soaked, not by rain, but by my shorts! Unlike the rolls, the b-17 needs somewhat level bars to saddle height. Try them both, they're both great in their own respects.
