From a combat tech perspective, yes in combat Horizon is very clean, but BOTW stutters and freezes frequently during combat. The image quality and framerate are better in Origins than Watch Dogs 2, on base PS4 at least. There is more weight to the animations now than in any AC before it, because the heavy weapons are heavier than they've ever been and unlike previous AC characters, Bayek really knows how to use them. There are things they can clean up, sure, but technically inadequate? Nah.
Unity and Syndicate had "city" stealth like AC2 - crowds, hiding behind structures/barriers, losing line of sight, etc. Origins has that, but also has more of Black Flag - crouching in grass patches, behind fences, and slow movement - but line of sight is still a factor. Every camp I've gone through so far - from the start of the game through the entrance to Alexandria - has had multiple line-of-sight blocking structures, and some have ample grass patches to crouch in. If you screw up a stealth maneuver, and they see you, there's no bias - they will come after you. But they can lose sight of you also and you can get another try at the stealth approach.
