The rs advantage on track will be its aero. And, in weekend warrior hands the differences on track will be subtle. But yes. Rs is rs....
The “regular” gt3 is more interesting to me and price isn’t the factor. mine would be pdk.

It's a useless marketing gimmick that's why it's gone. Replaced by Gorilla Glass that gets stress fractures. But seriously the pit speed limiter is like the fire extinguisher option, not legal for racing but it looks like it is.

Not worth the jump based on the price difference. The Nurburgring lap time is a matter of a faster track these days (repairs, larger runoff areas, repaving since 2016), combined with the super sticky Cup2R. If Porsche would take the 991.1 GT3 RS on Cup2R to the Ring today, it would run in the low 7 minutes, and no more than 7 secs behind the new car.
The old .1 GT3 RS produces the same downforce as the new .2 GT2 RS at 300kp/h. The new .2 GT3RS produces even more downforce than the .1 GT3RS, an extra 220# at 186mph compared to the .1 GT3RS or .2 GT2RS. 220# is a lot, that's actually the total downforce on the new McLaren 600LT.
Where the new car truly performs better is on suspension calibration. The new .2 GT3 RS has monoballs in all the suspension joints, except the rear axle steering joint, and flat aluminum plates on all 4 control arms. The .1 GT3RS had plenty of rubber bushings (same as the 991.1 and .2 GT3). This new car is all about a much better suspension, proper spring rates for a 3,000# car and massive aero (close to 1,000# of downforce at 300kp/h). This is where the .2 GT3RS (and .2 GT2RS) are making good lap times, their suspension parts and calibration (and even better with a DSC Sport calibration).
I have dozens of acceleration tests by now in both the .1 and .2 GT3RS on the same places (a drag strip and a service road). I ran a few exhaust configurations (maybe 8 or more), some of them made power, some others lost power, but once I settled on what I liked for sound/power/weight, the performance on the .1 GT3RS was better (power-wise) than what my .2 GT3 RS was doing bone stock. These days my .2 GT3RS is just a little faster on straight line, negligible but faster. My .2 GT3 RS is about 100 lbs lighter than my .1 GT3 RS, that has an effect on acceleration, the .1 GT3RS had Akrapovic headers and side muffler delete pipes, while the .2 GT3RS has side/center mufflers replaced with a JCR silenced race pipes (2 mufflers instead of the stock 3).
Where the new .2 motor is a lot stronger is in the low-range and the mid-range, but if you're on a racetrack driving on those ranges (below 5k rpm), you should buy a big block car or a turbo car.
Comparing the .2 GT3 to the .1 GT3 RS for track use, the answer is easy. The GT3RS allows massive wide tires and wheels, and once those get installed, the .2 GT3 cannot touch the GT3RS. The .1 GT3RS fits a 285/295 front tire under the fenders, and at the back any 345 fits with spare space for when a tire manufacturer offers even wider track tires. On tires alone, I have dropped 4-5 secs on a local 90 seconds track compared to the stock MPSC2 tires.
Depreciation-wise, a 991.2 GT3 RS already lost $50k in the last 6 months, and the majority of them (highly optioned cars) should lose another $50-$60k in the next 12 months. The .1 GT3RS would not lose more than $30k from the current prices, same should go for the .2 GT3.

Exactly why I went with a Touring. No wing envy whatsoever, but thoroughly love what's "under the hood"...!

You should try them at least once they don’t crumble after a few track days. Just use the right pads.

I just tell her it's hard to grow old gracefully when you've got 9K.

go with .2GT3 just for its engine itself. .1 engine regardless of regular or RS version has that stigma of Porsche **** up: And in fact that engine has design issues which in turn will exhibit in long run.
