I believe its the same. And the SSS ranks its all in 1 run, Style is pretty easy, all I did was wait for them to strike and demon dodges level 2, then spammed trinity smash lv 2 (arbiter YY hold Y) and easily got SSS on all levels on Nephilim.
Ill post my times so you can see one does get slightly better:
Human 10 hours
Son of Sparda 5 hours
Heaven or Hell 2 hours
Nephilim 3:34 hours
(Upgrades take a while since they are 79) I got my last upgrade on my current run which is DMD.
On a side note: the controls for the game were uber hard for me at first but with each run you get used to it and a lot better.
