I guess a lot of this depends on what you want in the car. Based on the reviews, it seems the G70 is more sporty, less GT, but it's also a lot smaller. In my youth (pre-40), I would likely prefer a more sporty ride and less space. But right now, I definitely appreciate the comfortable ride of a GT car and the Stinger is more than sporty enough for me. Perhaps this also has to do with how well it soaks up pothole ridden roads in the DC metro area despite having 19" wheels.
I love the hatchback trunk, and the space it affords, and it has plenty space in the back. I wish I could get the G70 steering wheel though. That's the only component that to me really feels out of place in the Stinger, specifically that center part of it that looks like it comes from a Kia Forte at best.
Still, I'll go back to the subjectivity. To me, the Stinger is just much better looking. It's unique, and I've never had so many people stopping me to ask me what it is. Not that I like that part, but I love the looks, the size, and the comfort.
