I actually use the Niuweidao : very fast (101) and powerfull (32) , long enough (88). But no pierce damage.
In his category you can use :
Elite scimitar : long reach, fast and powerfull (but no pierce dmg), I used it for many gens.
Grosse Messer and Langes Messer are good too.
Liuyedao : cheaper and faster. Perfect for low STR build.
Military Cleaver is powerfull
Italian sword : Good overall balance, probably my next choice.
Champion nordic is probably the best one, if you have enough wpf to be fast enough.
For 1h cav : Arabian cav sword, Knightly arming sword, Shashka
Axes : broad one : good but expansive
fighting axe : long reach and 2h weapon
1h war axe : my favorite axe, cheap and good enough.
Maces
Iberian mace
