I had a 997.2 GTS manual coupe for a year and 10,000 miles. The 911 has superb steering - you appreciate it almost as soon as you start rolling - and is very quick on a back road as you can carry plenty of speed in the twisty stuff. I also enjoyed having a 911 for a period and it was good to 'tick the box'. The main downside for me was noise - there is a lot of tyre roar, and wind noise around the windscreen from about 60-70 ; on the motorway you had to crank the volume up on the radio, or slow down to have a normal conversation on the phone (hands free of course!). Overall it didn't work for me as a daily driver hence just one year, but they'd be a great weekend toy.
I also had a couple of issues - clutch switch left me stranded on the drive and the horn stuck on once, which was embarrassing! It was taken away by the RAC twice during my ownership.
The RC F is a much better daily driver but not as much of a drivers' car. Horses for courses!
