How good is Planeta?

As the title says, is this basically the best for any unit that can take multiple commands and make kills? I am working on getting a V6 (or Whatever the weapon version of V6 is) for Sharkry and now I thatcI have a Tololo and Jiagyu, they both can use the weapon pretty well cause extra commands, would it be worth pursuing multiple 6's of this thing or just give them a 1 a piece and make only one V6 for whoever I'm taking into a mission?
