Well... this is virtually impossible to answer because "better" is in the eye of the beholder, and there are a lot of variables. For me, I would choose either the P3X or P5X frameset because I believe it is one (if not the) fastest and has lots of great storage. Here are a few other variables that folks might rank differently around the idea of better...

• Lowest drag (fastest)
• Easiest to travel with or maintain
  
• Disc vs. rim brakes
• Handling characteristics
• Ride comfort
• Integrated vs. standard brakes (if rim brakes)
• Integrated storage
• Integrated vs. standard cockpit
• Weight
• Bottom bracket type (some people may simply hate a BB, like press fit, threaded, or BBRight, etc.)
