The big fat tires on the back and weight balance mean most of the time the car wants to understeer, car really needs to be moving and on the power to get it play and then you're going quite fast, np for the track but tough on public roads. As Patrick noted, really need to commit to the power, hard to take nibble and enjoy like a front or mid-engine car on skinny / equal tires. I've had some time in 993, 997, and 991 turbos and GT cars and the right driver, better than me, can make them do incredible things... on a track. On public roads, not so sure.
Most fun Porsche I've driven that can dance is a Boxster Spyder with 4.5L 550hp engine. Mid engine, open top, stock street tires, really perfect suspension, and huge power mean you can slide the car around at legalish speeds at will. Coming out of my GT4 with stickier and wider tires and more aggressive alignment I hit an onramp in the Spyder at what was fine for my car but in fact way too fast for that car, understeer, power, oversteer, straight, power, tire spin, short shift to second, slow rolled into power, tire spin, short shift to 3rd, rolled into power, breathed for a 1/2 second and then more tire spin at 5k rpm, short shifted to 4th and finally merged onto the highway... and it would do that all day and in a very predictable way. So much more fun driving around town than my GT4, no question. Oh, and that was with the Porsche traction systems all on. I think if you want a 911 that can dance on the road, you almost have to go back to 996 or air cooled cars to get a 911 that doesn't come with steam rollers for tires out back
