Overall, I find Nioh to give you far more tools than the usual Souls game, but also not demand as much mastery of them. There's still some punishing mechanics (the only game that I've enjoyed doing the Exp recover after dying was Lies of P) and obtuse stats (even more when you consider the loot piñatas), but its still a game where I can go "All right, I don't want to deal with this" and use the Yokai transformation to melt a boss' HP.
Of course, at the end of the day, to each its own, so if Souls+Diablo gameplay doesn't sound appealing to you, its an easy skip.
Having played very little Ninja Gaiden, I don't think they're similar at all save from being 3rd person games. Nioh is much closer to the Souls formula, which slower combat, stamina consumption on actions and a demanding care on facing enemies, with the added complexity (though not necessarily added difficulty) of weapon stances and combos, skill trees, colored loot, and a Devil Trigger-like skill.
If you're going to try one, you should expect something more akin to Dark Souls + Diablo lootfest than the action romp that is Ninja Gaiden
I'm not in any rush, so I'll keep that in mind, but currently my plans for after I'm satisfied with Duke 3D is trying Dark Forces and the original Doom, both that I also haven't played in a few decades
There was a bluesky thread on games that scared you as a child, and I was reminded one of mine was Duke Nukem 3D. Since I haven't played it in over 20 years, I decided to look up that remastered version and you know what, pretty fun game still. The levels feel much smaller to me nowadays - even though they're fairly dense - but the guns feel good, killing enemies is satisfying, staying on your toes all the time hits just right. I also find it deeply amusing that creating a character was as easy as putting as many one liners from your favorite movies in the script as you can.
Picked up Nioh 2 on the PC, a game that I already owned for the Ps4, but now I'm trying the complete edition. Turns out that the DLC added new weapon types - and weapons in Nioh are far more intricate and complex than other soul-styled games - including a Fist type. Not only that, but literally the first skill you can learn is the Dempsey Roll! I feel cheated from having played only the base version. Maybe this time I'll actually finish this game.
