42 weapons of game version 3.3 in 12 classes, each ranked against the best weapon of its own class by damage per second at quality 6, worked out from the game's numbers rather than opinion.
The rule
Every weapon is at quality 6 with its hardest-hitting standard round (exploding arrows and bolts left out), no perks, no mods, attribute level 1, against a zombie at point blank. Guns, bows and launchers are scored by sustained DPS, the damage of a full magazine divided by the time to fire it and reload once; melee weapons by DPS, damage per hit times swings per second. Each weapon's score is divided by the best score of its class: S 85% or more, A 65% or more, B 45% or more, C 25% or more, D below. Ammo cost, noise, range, stamina and handling are not in the score; the reasons next to each weapon say where it stands out.
