Who cares?

It really just doesn't matter except for maybe bragging rights. I mean, unless you're talking about a significant weight difference, 1 or two pounds is trivial when you put a rider & water bottles on that thing.

A number of years ago (when I was riding a Ti bike) I found some german study that fatigued a bunch of bikes of different materials and Ti was definitely not superior to the other frames. I was disappointed at the time, having been delivered to the church of Ti is superior by my mistaken emotions but I got over it.
