>The superior nippon steel IS more or less better, right?
depends entirely on what you are fighting.
against most things? yes. against armored foes like shelled mutants or bots? no. you'll attack twice as often for a total of 2 x 0 = 0 damage. in theory, if you get BM martial art and a katana, it could be fine... but a wakazashi can't use BM.

>And the overall higher blunt+cut is less important?
it is important, but you should also think about your use case. do you really need to oneshot things, for example bots with full auto rifles? do you want the arts? brutal strike and sweep attack are amazing against dangerous enemies, but parry is always excellent and rapid strike is great for mobs.
ultimately the play is just try both of them out and see which you prefer.
