I have to vote wrap. In fact, the only carrier I use is a wrap, save for a MT very rarely. I only used a pouch and ring sling with my 1st DD (during her first year), but used everything with my 2nd . .and nothing, nothing beats a wrap, IMO, for fit, which is key for comfort. I never loved my pouches or RSs, but I just dealt with it. I never tried a wrap with DD1 because I couldn't imagine tying it in public-- I even had problems with the many POUCHES I owned-- but then I learned how to pretie. (And of course, with practice, it all gets much easier.)
It's funny how the carriers that are easier for most people are actually much harder for me!
