While I love the 2 Comp level one's I have, I would say no. Personally, I think you can find a much better value with other brands such as Fuji or Redline.
Yes, there is a huge difference between the frames and component levels between say a Sport triple to a S-Works. Each step up gets you better components and sometimes better frames. The Sport and Comps are both Aluminum frames, but I can tell you from experience, the Comp frame is MUCH nicer than the Sport model. So are the components. I've had a Sport model and currently have 2 Comp models and while the Sport is fine and a great bike, it was worth the extra $500-600 for the next level up for me. I didn't see such difference between the Comp and the Expert though. Sure, better components/wheels, but we're now talking about a level that I don't care about personally. You may feel the same way about the jump from Sport to Comp.
