I test rode both, and ended up buying last years Ruby Comp. I could tell a huge difference between the alum. and carbon frames. I did however, end up replacing the cassette that came on the Ruby, with an 11-28. I don't know if you live along the mountains of Colorado (although your username suggests that you do), the extra gears might help you with climbing the hills. I would just take them both for a spin and see which one feels better to you.
