Between the fuji being 200 cheaper and you being able to switch out stems, cogs, chainrings, etc., with your bike store (I assume they'll do this at a discount), it sounds like a much better deal. If you're going to be riding for pleasure, not racing, and possibly commuting, having quick access to a variety of stems, seatposts, and other components that will add to the comfort of your fit and, therefore, ride, will be a huge advantage IMO.
