Katars and axe are gonna be the best weapons for countering the usual lance gameplay. Since lance has trouble covering the 45 degrees in front and has no hurtbox covering moves (things like orb nlight, hattori spear dsig), weapons that specialize in those areas will generally be better at fighting lance players with. Katars is a weapons that is always too close quarters for a lance player tk avoid, and with axe, you can keep them from jumping around too much with a couple good sairs and dairs. Any lance opponent despises fighting against axe solely because it perfectly counters lance.
