Okay - you tossed down the sharp stick...
Here's what I see just wrong with the Mustang argument.... In order do get something that will "compete" -- you're in the GT500 or GT500KR --- not the GT model... and those cars are TWICE the cost of a Camaro.... and 50% more than a stock base Corvette that will kick their ass....
In the end - it DOES come down to $$ and what you like to look at...
