Each car you listed is much different than the next. The Audi has all the bells and whistles, and is a great cruising car. The BRZ handles great, but is low on power. The Z is a great handling car with some decent power. It has its quirks, though. It's raw, and will bite you if you're stupid with it. However, it's a blast to drive. In the end...just make a decision.
And for what it's worth, I couldn't disagree more. The Z blows both of them out of the water in the looks department. I'm biased, though.
