Best ATP Weapon in Episode 1/2?

[dnd]

Double Cannon sucks because of excessive rarity.

Red Mechgun and S-Rank Mechgun pwn the shit out of Yas9k.

IMO not, the yas9k has rifle range with 9 shots in east/wast tower ult mari group 1 hit deaths, wonder what i would do red mechs would kill it like 2 slots sooner but you would die before that, yas9k's are alot safer because you have alot more time to move around.

so the Double Cannon sucks because its really rare. so what about all the others then? do they suck because they are only rare, what about guld milla?
