Its pretty much the same as the fighter.
Pros
The ability to enchant its daisho gives it an advantage in low magic type of campaigns. Its not crappy soulknife type of enhancement either, it can put flight on it. Or turn it into an intelligent item.
It also has a better skill list with things like sense motive that gives and advantage.
Better will save.
Cons
Less combat suitable, due to less feats, and less choices for feats.
