I'm with Dragon on this. If you have never been a HP\performance junkie, you will be absolutely ecstatic with the V6.
Basically all you get with the SS is Raw power, and I mean raw. 430HP is quite a bit and takes some getting used to. And you also get the FE3 suspension. So, I'd say if you don't need/want the power and don't care for the sport suspension, get the V6 you'll love it.
Now, Just to be fair.

If you want to get your first HiPo car then the SS is a perfect choice.
