"Dude better move his face before I run into it."
Random sword thought ^^^.
Kinda depends.
A random warrior in the shield wall can get by with relatively inexpensive battle axes (long & short), spears/javelins, shield, helmet, and whatever armor he can afford or kill someone for & loot. The spear can go after chinks in armor as well as any other pointy weapon. A purpose-built knight-buster weapon like a mace, war hammer, or military pick ought to be pretty cheap. IIRC, the Welsh archers at Agincourt used lead-headed sledge hammers on knights that got into their defenses. Or was that Crecy?
A specialty pole arm would likely be issued purefleet in the mercenary band: glaives, fouchard-fork, halberd, ranseur, whatever. Lots of similarities between them, with variations on stabby, choppy, and hooky functions. As a (currently) unemployed mercenary, I would be loth to drag one of them around until I had work. Probably a moderate-length spear at most, pole-arm-wise, while unemployed.
OTOH, pikes and pole axes stand out a bit as a bit different. Pikes for being mother-loving LONG and necessitating close formation and the pole axe as being the other end, with a manual of arms more similar to a quarterstaff than most pole arms.
If one had the proper background, archers or combat engineers would tote other implements.
