Valid points. But, I'm really asking about mechanical and technical reasons to buy a GT2RS over a 720S or 488 speciale, as when the last GT2RS came out, Mclaren road cars weren't being made, and the comparable Ferrari was NA, and had much less torque than the GT2RS, and wasn't offered in a manual.
Now both Mclaren and Ferrari make cars (720S and 488/488 speciale) that with prices and horsepower both likely within 10% +/- of the GT2RS, and all three cars are turbo powered, RWD, with DCT transmissions. They've never been so similar mechanically in the history of the three brands, so that's the focus of my question.

Sure that is one clear difference, and was a bigger deal again with the last GT2RS which was so raw and had a rightful widowmaker reputation trying to handle that much power on two wheels with the 997 chassis.
But with the 991 body, the engine has moved farther forward and the 991 feels and drives more mid-engined than it used to, which is another reason I don't think the 991 GT2RS will feel as raw as the 997 version.
Just think about how much less raw a 991 RS feels compared to a 997 RS with the new 991 body, suspension changes, and PDK. I think that will also carry over to the GT2RS.
Basically, I think the GT2RS may feel a lot more like driving a 488/488 speciale or 675LT/720s than people expect.

But, totally agree with you that competition is fierce in this segment.

As to the 675LT, I think McLaren's brake-actuated LSD and hydraulic steering, not to mention its hydraulic dampers, sets it apart from most of its competitors.

You should move there, lol! Better yet, I heard Montana is even cheaper with zero sales taxes and next to nothing registration fees!

I think if the 991 GT2 RS does not gain any weight compared to the 997 GT2 RS (approx. 3000 lb) than it will drive very different from the 488, which weighs about a good 300 lbs more at about 3360.

I've been intentionally comparing the GT2RS to the 488 speciale which will be announced next year, and should drop a hundred pounds from that car, with power increased to 700hp and 3250 pounds, so the GT2RS will be about 50lbs lighter than the 488 speciale and 200 lbs heavier than the 720s, which is 2989lbs.
Agree that hydraulic steering, and a more advanced suspension are two key distinguishing factors for Mclaren. The extremely light body due to the monocell is key.
Really the best comparison is between the GT2RS and the Mclaren 720s. If you can afford the depreciation and running costs, the Mclaren is the better performing car due to its low weight, more advanced suspension, better steering feel, and incredible power to weight ratio. The GT2RS will hold its value better and will be more reliable and cheaper for track work, and have more consistent and easily modulated braking at track speeds. Also will attract less attention on the street than the Mclaren.

I think Porsche wants to take some of the current premiums for itself!

Burning Brakes
I actually asked this very question 2 weeks ago to a mclaren chief shop/tech manager at a mclaren dinner. Answer was that this was f1 technology trickledown which is a mclaren hallmark, and also that they save weight and have more precise control with this inside-rear tire braking tech. I can only add that 675LT brakes feel "wooden" in light applications, whereas the pccb feel more natural. Brakes might be one of few items I wasn't in love with on the mclarens, but they definitely seemed up to the job even on P1.

But joking aside... Isn't this what Porsche's PTV is.. exactly?
