I think out of the other RPG AC, this is the best. Granted it is not the old AC but it surely feels a worthy successor of the old series. The problem with Odyssey and Origins is actually on the narrative, and the way the story being brought to you, and I believe AC Valhalla fixed that. The way the story brought to you, the dialogues, and overall world experience is a lot better.
The stealth is also somewhat working (unlike origins and, uhm, odyssey). The combat somewhat feels more "weighted" and the enemy are not damage sponge, two factor that I experienced in odyssey. The only part about the combat that I don't really like is the Bosses, basically I just have to manage my distance and hack them slowly, carefully not getting hit by their "one hit", and that's it.
Can't wait for AC Mirage!
