720s with cup tires would probably beat the GT2RS. There are plenty of track tests where a regular 720s has beaten the gt2rs.

The 765LT will definitely beat the porsche. But there are other factors in which car you'd want to own besides performance. You will get insane attention in the mclaren, have much better ride quality on the street (hydraulic suspension), carbon tub, exotic looks, doors go up.

The GT2RS will likely hold value better, have less problems, cheaper to own out of warranty, and be more understated. Not to mention mclarens service centers are few and far between compared to porsches.

The 2016 Mclaren 675LT MSRP'd for nearly $400k, now you can get one for just above 200k.

2011 GT2 RS. MSRP $250k. Now selling for 300-400k.

Just something to think about.
