Hey folks,
I'm planning on setting up a touring rig in the next few months. I'm a vintage Trek guy, and I've only ever owned Treks; naturally the 2014 520 got my attention (it is beautiful!).

I do, however, have the ability to build up a (presumably) 1989 properly sized 520 frame instead. Money, vintageness, aesthetics, etc. aside, which is a genuinely better frame? Any input on the subject is appreciated!
