This car will be at the 12C/458 price bracket, a step up from the 991 Turbo S.
But then again, the 991 Turbo S is a different beast from the other 3 all together, the Porsche is the incognito car, the other 3 are the flashy look at me cars, so depending on personal tastes, they don't really compete with each other. For some, they will buy the 991 Turbo S AND one of the other 3 just because they are so different.
The V10 at least of the displacement advantage going for it, to provide some much needed low end torque. A lot of people believe the throttle response of NA is horrible, especially at low rpm. They never have the immediate power delivery on any rpm from turbo/supercharged engines. Depending on point of view, that's the throttle response people are looking for. With small to medium displacement NA engines, especially those that tuned for high rpm hp, they have horrible low end torque, you press the throttle and 2 seconds later the power arrives when you hit 7k rpm from 2k.
Even the old AMG 6.2l has inferior low end torque compared to the 55k engine and it's already a big displacement engine. On the 55k one only needs to touch the throttle and the car jumps. With the 6.2 the engine needs to be winded to at least 4k rpm before any meaningful power is produced.
