As has been mentioned. It ultimately comes down to what you will be happy with. I chose to go the XR8 route and I'm extremely happy with it, and it's only getting better. 11000 k's and starting to really fry the tyres !!! By the way, as I've noticed on this forum, there are way more problems to be reported with the 6T then the 8. Herrods exhaust will get it bellowing Good luck, either way you can't go too wrong, beats GMH hands down.
