as been mentioned ride what is comfortable to you. i loved my carbon road bike, but my 1958 holdsworth is way more comfortable. in terms of performance i don't think it is the massive difference that what everyone makes it out to be. heck, at rolla hillclimb i rode faster than quite a few roadies on plastic bikes, this is on a 50+yr old fixed with mudguards etc. flexy stem, flexy this and that, old technology; you can still get shit feeling and sloppy modern bikes, throwing everythign in the same basket is crap.
