can someone persuade me?

i already know I'm getting a tibu (loved the car since I've been a kid) but I'm torn apart in which trim i should get.

should I get the GS or the GT? for me the lower mpg isn't something I'm looking at
(i already drive a V8 premium only so a V6 is still a step up for me)
So is that extra 34HP really worth is?
