best mech gun?

[Tycho]

Yea, if your in Hard Mode, Twin Psychoguns are awsome. Get a pair as fast as you can.

That's because in normal any weapon type is great (well, still except Inferno Bazooka, Drill Launcher, Rocket Punch, S-rank Punch and Belra Bazooka), that does not mean Twin Psychoguns are good.

Cannot get charge on s-ranks and Beserk and Spirit are wasted
Just hunt a pair of Vulcans with Hit, and beserk, or pipe charge!

Could you explain why Berserk/Spirit would be wasted on an S-rank Mechgun (even though M&A60 Vise would do the job as well, since it can have hit but despite its lower ATP)?
Also, M&A60 Vise is a lot easier to get with hit than a Berserk Vulcan with hit. X_X
