The Jamis is more of what I'd call a speedbike, whereas the Bianchi looks more like a leisure bike. Those swept back handlebars aren't designed for speed on the Bianchi. Also, the fork looks threaded with an old style stem.
I suppose it depends on what kind of riding you plan to do. 7 miles isn't exactly a short distance, so I think riding the slower bike would get "old".
If you're near a Performance Bike Shop, you might want to give them a call and see if they have any 04s Jamis' left. The price should be pretty good and you can get 10% back in store credit if you join their buyers club.
