Most Wanted is definitely more fun than Undercover. I'm #4 on the list now, and the work you have to do before you can race the big names on the list is in a lot of cases tougher than racing the bosses themselves. The cops are vicious and persistent, and in races even if you fall way behind, you can sometimes catch up and win in the last 5 seconds of the race. In Undercover, getting away from cops and winning was hardly a challenge most of the time, which is fine but not very compelling.

No GT-R in MW, though even fully souped-up in UC, it didn't perform as well as a Porsche GT2.
