It definitely is not. There are plenty of areas where tearing rears its head - particularly at night. The PS4 version is far more consistent overall.
With the AF issues that seem to occur in a lot of games for both consoles is there any chance you could speak to some devs about this to get some actual feedback as to why this is turned down or off. It is even more puzzling here where we know that a) 16x AF seems to work on the PC with no issue, b) the Xbox One version does have AF and c) the PS4 has more memory bandwidth so should suffer less from AF than the Xbox One.
I just find it really strange and I have not come across an explanation that seems plausible.
