The timing of the question is fortuitous as I had both of the cars on track this afternoon in Italy. Based on my experience (approximately 20k on CGT and 4k on tdf, split between track and mountains), I would suggest that the driving characteristics are quite different beyond the initial sense of rawness. The CGT is really two different cars depending on whether the tyres have been upgraded from the original Michelin PS2 to SS released a few years ago by Porsche. Prior to that, I had a car whose sensitive on-limit handling required circumspection on the road and plenty of run-off on track. Exciting for sure but very difficult to run consistently at the limit. Post upgrade, it shares many of the driving dynamics with the F50 which make them among the best manual supercars made: taut chassis response, flat cornering, rich steering feel, and amazing engines. The F50 edges ahead due its lightweight go-kart style response through corners, and and and even better engine even though the CGT brakes are a testament to the massive improvement from ceramics in the approx 10 years between the cars. Without the electronic nannies (PSM - Porsche stability management) on the CGT displays typical mid-engined handling: neutral to mild understeer on the way in, adjustable on throttle mid-corner and snaps into oversteer beyond the limit which requires quick, accurate correction. The tdf behaves quite differently in that the turn-in is immense for a large front engined car, and you can delightfully oversteer around the entire corner if you get the balance on its knife edge, but the inputs need to be correctly metered and precisely fed in. Unlike the CGT/F50 mid- corner throttle corrections can easily induce more oversteer. I am still very much at the start of the learning curve, but it is an amazing journey, and fundamentally very different to anything I have owned including the earlier F12 and the later 812. The need for electronic handling aids is perhaps the biggest similarity between the tdf and CGT - both appear to be designed to be driven with them on, at least on the road. The static stability is relaxed by design to allow super sharp response but the aids keep it within limits. I have just about graduated to CT-off on mountain roads but ESC-off is a step too far. I have seen comments about the unpredictable handling on both cars. I prefer a sharper knife and learn to use it correctly (and mind my fingers!) I agree with the post above that the tdf will stand independently to the other V12 limited editions. The answer lies, at least in my mind, in its sheer force of personality which is much more than the sum of its parts. Given the seismic changes underway in regulations and the market, I doubt we will see its kind again. Not sure how any of this helps the OP, so apologies if off topic.
