The bike itself shifts more quickly and smoother, or the new/better component group shifts more quickly and smoother?
Higher priced bikes usually have higher priced groups. A Specialized bike priced around $1500 probably doesn't have the newest/latest/top-of-line Shimano DA or SRAM Red or Campy Record. It probably does not have the lightest faster hubs and wheels. So components have a lot to do with price.
After components it's the frame. The more custom the more labor involved to produce. And where is it produced? A Ti or steel bike hand-built in USA will be an expensive hand-built frame. Some of the new carbon frames sourced in Asia and sold by big names like Trek and others you're paying a premium for the name.

It shifts increadably quick and smooth. It accelerates quicker and handles better.
