Saw the 991 Coupe at Rennsport. Wasn't at all drop dead impressed (OTOH, the 918 is even more impressive in person!) Lets assume the 991 is a great performer and beats the 997 in every way. How important is it to you to have a car that goes 10 seconds faster at the Ring, or gives you a tenth of a second in a turn? I'd have no problem sacrificing that for a car that looks better (which the GTS does). But that's me. Like Siri says when you ask her if you should get an Android, "You already know the answer to your question!"
