I think the recurring theme is that you'll never know how comfortable (or not) they are for you unless you try them. I would recommend that you don't go with some cheapie bibs, if you can at all help it. My first pair of bibs were Performance branded bibs. While the Bib portion of it worked great for me, the chamois part didn't give me the right support. Granted I kind of knew it since I owned a pair of the Shorts version of the same (hence I own both the shorts and bib version). Bibs are more comfortable for me. When I decided to spend a little extra on the higher end Bibs, I found them extremely comfortable! My advice is go find out for yourself!
