The 5.01 GNB SFX seems to puts more focus on the slashing/slicing sound and the explosion sound rather than than the constant clanking that 5.00 GNB SFX but because they got rid of the "bang" part like you were firing a gun, the dip quality became that much clearer, because 5.01 GNB SFX is only missing the "bang" part which seems to be the thing I want more but that's just a me thing...
