Both companies make good bikes. I own two Treks (one road bike and one mountain bike) and my husband has two Trek mountain bikes. He also has a Cannondale road bike. Unfortunately that was an impulse purchase and he should have done more research since he has never been able to get comfortable on it. We're actually purchasing two Felt F5s, one for him and one for me. I've been wanting a carbon bike for awhile and when looking we found that the Trek and the Felt road bikes are much more agreeable to him than the Cannondale is. So all of that to say yes I do believe that some people fit certain brands of bikes better than other ones.
