I think it's important to remember that Drive Club is tethered to PS+ as a way to increase subscriptions for that service. Or, at least, I'm pretty sure that was the plan in the beginning and it's too late to change it now.
That being said, I'm still going with Drive Club, if we include digital. The PS4 will have a much larger installed base in Europe, which I think will be the difference. The XO already has a racing game under its belt, as well.
