Mustang seat differences

What is the difference between the standard Mustang seat and the "tuck and roll" version?..I know the costs are different, but is the extra money for the tuck and roll worth it or is it just for looks??..Is one more comfortable than the other or does it really matter and is more of a personal choice...Getting ready to order mine next week and just curious..All opinions and comments welcome.....

I asked Mustang and a distributor, both said no difference in comfort. just styling.
