If you're not secure with your manhood then get the 6MT.
Ok, all kidding aside. Each has benefits and downsides. You need to make your own choice. I got the 7AT and love it. Do I sometimes wish it was 6MT? Sure, of course. If it was just a pleasure car I would have gotten the 6MT. However, this is a DD for me as I have another car to run gears through.
Don't let fools tell you there's no such thing as an automatic sports car. That's just a lame way to think. That's like saying all hot girls are a pain in the a$% to deal with.
Oh wait...
