Back when I was a kid and used to play 1e, I'd use polearms all the time. The Spetum & Ranseur, because they could disarm opponents. And one time I had a character that used a 26' pike.
Of course, the thing is, swords are the most common weapon for a reason.
The History Channel had a show called "Conquest", and on one episode of it, it featured all sorts of medieval weapons, and the reasons behind why they were developed and their various strengths/weaknesses..
Basically, the sword is the best overall weapon, in terms of maintence, durability, effectiveness, and ease of use.
