Not gonna lie, I don't know or care which games belong to which genres anymore.
I suppose Sekiro is a "better" game than any character action or hack and slash I played, including Devil May Cry 1, the king of the "genre" when time and impact are considered. But DMC in 2001 was truly something special, it remains my tied favorite Capcom game alongside RE1 Remake, and both should have sold at least 10 times more.
I noticed that the older I grow the less I care about ranking stuff. Sekiro and DMC are different games from different eras. To me, no modern game is as flavourful as DMC was back then, but I recognize that my taste buds aren't the same.
Anyways... some of my favorites include DMC (definitely not 2), Onimusha, Shinobi (especially Revenge of Shinobi), NieR Automata, and Sekiro if it counts. I was never a huge fan of God of War, I didn't enjoy Bayonetta 1's demo enough to buy it, and I didn't play Ninja Gaiden more than 10 minutes and instead enjoyed watching my brother play through it. When one of us played a game, the other would often skip it.
