I kinda have to disagree. Although one could be faster in a 997s due to their lack of professional skill in handling a GT3, you can get so much more performance laden enjoyment from a GT3. Not to take anything away from the 997s, but the stiffer suspension of the GT3 as well as the dry sump motor makes it much more accessible in terms of performance driving.

Even if I went slower in a GT3, I'd take it over a 997s as a weekender car (not as a GT or a daily driver)
