I was at the same spot as you a month and a half ago. All depends on how ones feels the bike. I tested a few brands at the same range as you (Trek, Cannondale..), and decided to buy the Specialized Croostrail Sport Disc at $710 model 2015. The day I tried it I just couldn't believe it how great it felt.. I simply love it and enjoy every second my rides. My advise is not to go for what you simply had in mind but the one you FELT IT better. Best Wishes on your decision.
