Does a Knife with lubrication cut/stab/slice/etc better or worse than a Knife without?

It would not appreciably effect the cutting power of any variety of knife. What it would be is protect the blade from tarnishing. The force applied to the blade perpendicular to the cut is what causes the friction. This force is from the sides pushing in on it. While lubrication would make the coefficient of kinetic friction between the blade and the object being cut lower, what slows a blade is mostly the object in front pushing directly back on it. It would certainly not hinder cutting, but the reduction in friction is nominal in comparison to the force required to cut an object. This being said lubrication would help sharper knives more than dull knives because the force to cut forward is lower, and as such friction may come into play, albeit barely. As stated earlier the lubricate makes sure that liquids don't accumulate on the blade and cause it to rust, although you should still keep your knives clean.

TLDR: Not really, although the sharper the knife the more it would help.
