Technically PS5 and I think Switch 2 is based on the BSD kernel probably because of the license. Xbox is not exactly Windows but it's using an NT kernel.
Playstation is FreeBSD, yeah, but the Switch runs a completely bespoke microkernel. Nintendo did borrow the BSD networking stack, which led some to infer from the license disclosure that it runs a BSD, but it's been extensively reverse engineered now and it doesn't even vaguely resemble Unix.
