Depends on where the boosted slots are and how close they are to each other (i.e. if there's a 2x2 square it's going to be insane, if they're all far apart then it's much less valuable).

That said unfortunately even the niche pistols fit in before have been power-crept significantly when they introduced atlantid multitools (does everything a pistol does but better).

That said once you get a decent multitool the difference between them is fairly minimal (I personally stick with sentinal versions because I can install a second mining laser onto it and mine at double speed).
