Monk bo staff of trorsmang vs facesmasher

[Troxx]

Bo Staff ratio of 1.2 (better ratio)
Facesmasher ratio of 1.14 (worse ratio)
Bo staff faster thus better dmg shield returns
Facesmasher slower, opposite of the above

Really simple calculator action there ...

Bo staff has undeniably better dps, but facesmasher has 25ac, 100hp, 15 more str and 15 more stamina.

Do you want your weapon to give you more dps or more stats. That's really all this boils down to.
