I believe that the bicycle business is pretty competitive. If you go to a bike shop, I think any bike you see with 105, ultegra or dura ace will be a good bike. Now some bikes have kind of plain vanilla frames to get the components and others go the other way. Even so, I think the frame gives more of a "feel" to the ride and not a whole bunch else.

I have put quite a few miles on aluminum and now a titanium frame. Both work fine. I have never ridden a CF frame. But I know plenty of people who do who really like them. But there are some people who like chocolate and others who like strawberry or vanilla or pralines and cream (in ice creams of course). I think something like ride "feel" is like ice cream flavors, pretty much a matter of personal taste. I would suggest that you go and ride some CF and titanium frames and see which you like better.
