I have a Ruby Pro, 2007. I am not sure what changes they made for 2008 in the bike, but I LOVE my Ruby. I went from a Specialized 2005 Dolce Comp which I really had no complaints about, but I just wanted a smoother ride and the Ruby gives me that and have seem to have better control over the bike in areas of rougher terrain. The bike is quick and responsive.
I cannot comment on the Trek as I never rode one.
