I own both and I would prefer to drive my 5th gen over my 6th gen based on how much more room I have, but with a 6th gen you just get a much nicer and newer interior, I like my 5th gen exterior more especially once I get everything install. But I drove an ss 5th gen and compared to my 6th gen. There's a noticeable difference on how much faster the 6th gen is, also a noticeable difference in price as well. You can't go wrong with ether one. Completely your choice
. I say get both
