Does Higher psi in X-valve is really better? Interest in higher psi reg than 800?

I am using an Apocalypse on my Emag and it makes a big difference (well, at 1000 psi). The marker is able to live up to it's potential with it.

I'm using a NitroDuck Ireg with the 1K output piston. It rocks.
Even prefer it over the G-Force frame
