Would you get new GT3 without PCCB?

PCCB's aren't necessary, but if not a 'dedicated track car'... I'd choose PCCB every time (and did). For me, it's about the 'straigthline acceleration' benefit the most. I'll do a 1/2 dozen events a year at the most... and so far, my pads and rotors still look like new. The aftermarket ceramics are a great alternative but will 'start' out more in the beginning.

As others said, stopping power same.
PCCBs have no dust, last virtually forever with light use (regular street use and rare track use by average drivers), and look great. But they're expensive up front, and very expensive to replace when damaged, which is a real possibility with frequent hard track use.
Irons have dust and wear out sooner but cost a lot less to replace, which is a big reason why those who track a lot prefer them since brakes are consumables to them.
PCCBs supposedly resist brake fade better under hard track use, which is probably a non-issue for average drivers who do only short sessions on track and who don't push the car ten 10ths. PCCBs are also lighter, so some say they improve handling thanks to lower unsparing weight. Probably, but not everyone may notice.
I test drove a 991 TTS with PCCBs alongside my 991.1 GT3 that had irons. I couldn't feel any difference, but then again, I wasn't going gonzo on track either. Put simply, you won't notice much if any difference in most driving situations.
Having said all this, I ordered my 991.2 GT3 Touring with PCCBs, which will be my first Porsche with them. Why? Well, I won't be tracking the car except maybe 1-2 days per year, and when I do, I'll be doing brief (20 min) sessions and am not a pro. So I'm not worried about wearing them out. The PCCBs look spectacular, produce no dust to tarnish the silver wheels I spec'd, and should last nearly the life of the car. And I figure they'll be desirable on eventual resale on a GT3 Touring so it'll be close to a wash for me in the long run.
I guess, I figure this: If you're buying a GT3 to push it hard frequently on track, get the irons unless money no object for you. If you're buying a GT3 for spirited driving on street and rare—if ever—track "visits" for short sessions at less than ten 10ths, and if you also like the way they look and value no brake dust, then spring for the PCCBs.

I was told less dust is not because of ceramic rotor itself but the ceramic pad. I attended the Ron Fellows Spring Mountain Performance Driving School and they intro the Corvette and talk about CCB. They said ceramic pad can be used with iron rotor or vice versa. The ceramic pad will perform better than metallic pad even on iron rotor and about 80% less dust. If it's true, perhaps I will just replace with the ceramic pad on iron rotor.

BTW, does GT3 or any 911 equipped with something similar to Corvette's Performance Data Recorder? Basically recording your performance and video just like Herry's Lap Timer?

Yes, and I did, but it's personal.
Light track or only street use I would have picked PCCB but I like to go to the track often and even maybe buy a second set of tires in 19" to have a wider range of tires. (almost imposible with larger PCCB rotors)

I do not worry much about resell value because I am going to keep it for at least 5-6 years and could be more.
Thank you very much for all your inputs.

RED BRAKE CHANGE OUT
I love my PCCBs on the last 3 GT cars but after talking to an early 991.2 GT3 owner complaining about caliper-to-inside-barrel distance I've decided for the GT3T I'm going Red Calipers and looking for a Rotor/Pad swap to aftermarket CCBs.

One of the biggest advantages of PCCBs is that you don't have to swap pads for the track and they don't squeal on the street. This may be possible to replicate by using the PCCB pads with steels as mentioned above, but I don't know if this is possible. Swapping pads with this horrible caliper design is a major PITA.
