You know, if you are talking about fun on the street, the crossfire isn't much worse. If the srt6 was available in a manual, I'd have a hard time choosing between the two. The evora is a much purer driving experience, but the srt6 would likely be much faster in street driving. On the track or technical back road driving, I'd most likely choose the evora over any XF. However for normal street driving, I think the crossfire is a bit more fun.

If the srt6 was available with a manual and had steering that was a fair amount more communicative than it is now, I'd likely rather have it over the evora for almost any situation. I found the z4 coupe to be vastly more fun to drive on the street than the evora. Of course, my tune would likely tune when the evora is really pushed towards its limits compared with the other cars mentioned.
