Honestly I do not see anything in most porsche models and do not see a reason to choose cayman s over the SRT although it was one of the cars I considered before I purchased my srt. They way I see it is the is porsche hasn't significantly updated their styling... ever and the crossfire has a new interesting design which will get you more attention.. if that is what you are going for.

SRT is made by Mercedes and AMG. and porsche is made by...um... porsche In this case again to me the SRT wins again. And lastly is the price the SRT crossfire can be had for 27, 28 new, why pay twice for a car that has no advantages over it.

The only salvation here is.. Cayman comes with manual and if thats what you need and want that is a good reason to buy it over the crossfire.
