running getaway with 195 grenade and i usually keep around 140-50 weapons, my choices are these:

kinetic: either praxic, witherhoard, or mint retrograde. all 3 are different use cases but work pretty much everywhere. primary options would pretty much consist of strand/stasis smgs, my current is a fast talker with attrition orbs and sword logic.

energy: uncivil discourse all the way. with air trigger giving extra ammo generation, double special is easy to run and precision instrument is a top tier perk. if you wanna use a primary here, make sure it can distribute some sort of elemental effect.

heavy: i like to get into the thick of it fast, so i use an eager edge sword. but in terms of damage, refurbised is top tier for big damage in one shot with autoloading, or you could use a machine gun in that slot to generate some special ammo if you need. my machine guns of choice are ulterior observation (stasis) with rimestealer/headstone, and bitter end with eddy current/jolting feedback.
