The components on the Comp are lighter, more expensive and offer more gears with less range and tighter tolerances. The wheels are lighter with fewer spokes which means they're likely less durable. The frame's got more carbon and more material joins. Better? For a heavy new rider? Not by my reckoning.

Lightweight racing components are nice and all, but no way is the more expensive model going to have the durability and low gearing that make for a good starter.
