I was looking these weapons for the sake of curiosity...I think Hauberds have an edge over lances due the belanced damage type, which offers a more constant damage against any enemy with both basic attacks and WSs and also having a much better delay. This makes, IMO lominsan Hauberd the overall best weapon.

Champion is great too, but the thing is actually getting the HQ version of it...if you can and will focus on piercing damage, its the best one...if not, i agree with Scape...Bannaret is actually a better option due 100% piercing and a better chance of finding +2/3 for a decent price.

I don't like Guisarme...its damage type isn't good (would be way better is the 20% blunt were also slashing) so, by looking to it, damage type, effects...i'd say its more of a solo weapon. With evasion bonus, DEX, PIE and an weapon that has blunt damage over slashing they are saying "Hey, go solo a bit...we will support your evasion setup so you can succefully use cross class damage negation and retaliation actions".
