Got an S1 and a 996 Turbo. Totally different cars that satisfy totally different moods and driving requirements, wouldn't be without either (unless I replaced the 996TT with a 997TT).
First thing you'll think when you get in the Porker is wonder why the steering wheel is such a stretch - always happens to me - and the second will be how quiet it is. The real World on the road performance difference between the two isn't that great below 100mph, unless it's raining or snowing.
Uptopia, of course, is one of each, the 996 being the sensible one of the two
