Most hated weapons?

For any reason at all, really. I'm nominating the Tepoztli as Bastard-Maxxed Son Of A Bitch From Hell on account of it being able to two-hit you even with 50 Cut resist if the Quasimorphosis meter hits about 800. Mostly carried by the female cultists who, due to being women, gain an AP advantage to offset their low chances of joining the NBA, and can thus sprint you down and then chase you forever from melee range while always being guaranteed a hit.

I'm also raising the Eagle series of guns as being "kind of ass" with "no vibes" because their entire purpose in the world is being unloadable for .42 ammunition and having an almost distractingly simplistic sprite compared to every other weapon in the game.

Finally, we've got the Builder for "I fucking trusted you" because despite being good damage, great ammo type, cool concept, and easy to find, it also actually has so little accuracy that the nails will perform previously-impossible physics acts such as falling into a backwards arc through quantum space to miss an enemy literally in the tile in front of you on your last AP.

Legacy is also an honored mention because, as cool and good as it is, I've never felt the ass-freezing primal fear it instills upon me when I walk into a room and a 2AP enemy suddenly dumps ten bullets into my head through a map tile that should have been blocking half of his shots.
