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 piรฑatas), 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.
Congrats!
