The thing about spears in one-on-one is they actually have a gross advantage on swords in reach, because the grip varies. It isn't always 'one hand close to the middle'. With a six-foot spear - honestly, perfectly average for a 'fighting', twohanded spear - one can thrust with hands very close to one end while still maintaining control (the grip shifts a lot...even standing there, one hand at one end, the other hand close to the middle, someone skilled with a spear can change that grip in an instant by sliding the spear, and suddenly that already-large reach gains another foot or more on the thrust). The reach is far outside that of a sword, and it's dangerous on the retraction due to the cutting edges.
There are things swords do a lot better than spears - defend, for example - but that reach advantage is quite hefty.
And having done a LOT of weapon sparring with weapons of different length, I'll say that 'just' a reach advantage of a few inches is enough to make a difference. If it's a foot? You're looking at the only way to immediately threaten the other guy from outside of his reach is with a long, over-extended thrust which will could get you killed if it's avoided (and I like to assume the other guy holding the weapon isn't a tyro).
Otherwise you need to move through the other guy's reach just to engage him.
Which...is not ideal, barring you having some really good armor.
