I would get a 488 GTB or 812 Superfast over the GT3 RS any time...unless it would be the new GT3 RS. 

it is gong to be an incremental difference to the 991.1 GT3RS

Truth be told though, I would prefer a car with AWD...or a McLaren (excellent TC setup).

AWD is a good point, but none of those cars have AWD, except the lambo. 

The 488GTO could be a resale/value winner though, same goes probably to the 812 Superfast.

yes possibly. but that is what people thought about GT3RS.

If I had a quarter mil Euro now, I would probably choose between the Huracan Performante and the 720S in a very basic setup.
