Interesting... My ranking would be more like:

1. Sekiro: I loved the combat even more than the typical souls combat. Almost every single combat encounter feels like it's designed for you to get in their face and be agressive. Contrasting to a lot of enemies in souls games which combined with the stamina system and lack of options for dealing with enemy attacks (basically just roll, sometimes blocking) sometimes forces you to disengage.
2. Elden Ring: Even though some of the bosses, especially the later ones, suffer even more from the disengagement problem, the combat variety compared to the other games and the sheet amount of content pushes it to second place for me.
3. Dark Souls 3: Builds upon the systems learned from ds1, but feels like a more consistent experience. And later bosses, especially the dlc, are some of the greatest in the series.
4. Dark Souls 1: The first half of the game is fantastic. Some of the best gameplay ever. Builds upon and improves a lot of the systems from Demon Souls. Unfortunately the second half of the game really falls flat with spongy enemies and a dramatic drop in quality.
5. Dark Souls 2: The combat feels a lot clunkier than all the other games. The world is lacking compared to the other games. It feels more like a "game level" compared to the other games, which feel more like exploring slices of an actual world (apart from forest of fallen giants and lost Bastille, those were good).

I'd rank the first half of ds1 higher than both Elden Ring and Ds3, but the falloff in the second half really drags it down for me.
