Simply put the forge splattershot pro has the best toolkit.
Suction bombs are really good for midfielding because you can dump them and run, or dump them and reposition, preventing the enemy from pushing through.
Bubble Blower also works well to that extent, blocking enemy projectiles and covering the midfield.
The regular splattershot pro has ink storm which is useful, but point sensor does absolutely nothing for clam blitz.
The Kensa version has splat bomb and booyah bomb. Booyah Bomb is good and all, but if you're going with an aoe special like that, why not do it on a weapon meant to be on the offensive? Splat bomb is also meh for midfielding, it explodes too fast and doesn't provide enough zoning.
