All I can say to that, is that PS3's UFC Undisputed 3, undisputedly has much more immersive/responsive/satisfying Finish the fight sequences compared to any EA SPORTS UFC game of the PS4 Gen.
Only thing that EA has come close to competing with that game's Finish The Fight Sequences, was EA UFC 2's KO Physics. Overall they weren't better or more realistic, but they were unique, they were fun and they felt like the next-gen leap we ought to expect.
Then they completely scrapped it, instead of working on it and we got some worse than Undisputed 3, canned animation/finish the fight sequences, that are not responsive whatsoever.
