"Better" is a very subjection frame of reference. People prefer whatever frame material they prefer based on what priority they place on the characteristics of each frame material. Some of those are flex and stiffness, vibration absorbtion, durability, weight, etc. It would be very difficult to say which is better without knowing what you are looking for.
Which is better, a chainsaw or and X-acto knife? Depends. If I want to cut a tree down, the X-acto isn't going to do the job. If I want to cut delicate plastic model parts from the sprue...well the chainsaw will just tear things up. So which is better?
