It's not a fair comparison in my case. The Allez is from 2008, originally had heavy wheels and sora. The Evo Supersix is 2014 and cost 4x with much better components and wheels.
The Evo is noticeably lighter and better looking.
Both have a similar race geometry, and I've used both for commuting, fast group rides, and 100+ mile rides.
I've upgraded the Allez, and am still quite happy with it, particular since I can run square taper BB, which is needed for my powercranks.
