Daily driving PCCB vs. reg brakes- can you feel a difference?

In my experience, PCCB has significantly worse stopping distance when rotors are cold (when near freezing outside).
When warmed up, stopping distance on the street is about the same as regular/steel.
On HPDE track sessions with multiple braking from 130 mph to 40 mph (PCCBs should be superior in this use case), I am unable to tell the difference. Maybe if the session was 1 hour, I’d experience brake fade on steel, but I’m just a casual California Porsche owner and not a hardcore track guy.
But hey, the calipers/rotors look cool and produce no brake dust. Is that worth $9k? Up to you.

Went from no dust to literally the brake dustiest car that ever existed. it was a MUST 9k, 90k....

I don’t think I could tell the difference. As outlined above the main benefits in my opinion, for the carbon brakes are the lack of dust and the reduced wear.
that being said, I’ve had seven or eight Porsches, and never done brakes ever on any of them. Of course I don’t track my car but I do drive them.

992 PCCBs are dustier than 991.2, I can verify. The old ones were completely dust free.
New PCCBs are still less dusty than iron, just not as good as the old ones.

BMW brakes are known to be the dustiest mother****ers around. It's honestly appalling.
Anyways, largely agreed that while the pedal may feel different, the practical difference in stopping power even on most tracks in a 20-minute session is negligible at best and probably imperceptible. The unsprung mass, on the other hand, is probably very noticeable but I haven't driven a car with the standard brakes back-to-back to compare. I imagine there is more grip/performance available with the reduced weigh that a skilled driver would eke out, but even a less skilled driver would probably notice a difference in steering feel and behavior over uneven pavement on a track with PCCBs.

Thanks everyone for chiming in your experiences. I learned a lot from hearing what you've all experienced with it. I'd love to try PCCB one day and see how it feels.
With that said, I wonder if a lot of new buyers just click PCCB assuming it's better. Based on what I gathered from reading above (and pending lack of person experience w/ trying PCCB), I almost feel I would never order PCCB. I predominantly drive city and occasionally drive highway. I would hate to have to drive and to remember to "warm" up the brakes. I just want to step on it and have it work when I need it. Don't see any big advantages and wonder why everyone goes for PCCB.
I'm so curious whether many new buyers even know what they are getting themselves into with PCCB. Bc despite being able to regurgitate every spec option this knowledge I did not have despite being an owner for almost a year.

I would never order another car without PCCBs if they were available.
ordered a 992 T. Only thing I wish it had was PCCBs. Will miss those when I trade the TTS in.

+1 to @dixonk. the only real downsides to PCCBs are:
1. initial cost
2. replacement cost, if you track and actually wear the rotors. on the street they will last ages though.
If it's not a money issue I'll always get CCBs for the brake dust alone. Washing wheels is the worst.

I prefer washing my own car anyways. Just not the wheels.

Some of us want to match the color scheme. Yellow looks great (esp on carmine, look at the press GTS cars). They just look fantastic. I'm not concerned with fade, track etc as the cars have so much capability that I will never use to its fullest.
