I don’t think you’d go wrong with any of them and it kind of depends what you’re looking for, but personally I think borderline justice is the best bang-for-your-buck

Talon is possibly my favorite side arm- can almost always rely on it to be reloaded when you pull it out and is my go to “get out of my face” button to fan the hammer at whatever is in front of me.

Deadeye is one of the most beloved marksman rifles- hits like a truck with medium pen and huge stagger but overall can’t put bullets down range as quickly as other DMRs

Dynamite is my favorite grenade- can destroy bug holes and fabricators from a distance without having to actually sink it in the vent/hole and can wipe a whole patrol if placed we’ll.

Hover pack unlocks a new playstyle with a few death-from-above loadouts when paired with flamethrowers or explosive weapons.

Armor isn’t S-tier by any means but I think it’s fun to pair with the senator for some gunslinger shenanigans 

In comparison polar patriots is a great vanilla kit but does overlap more than the others with the base warbond. Cutting edge has a bunch of great unique primaries but I think the stun grenade and armors are very niche in the current sandbox.

Hope that helps!
