you're out of arguement very fast.
A: usu body + sword strap+ usu feet
B: hauby+1+ pole grip + usu feet
C: usubody + pole grip + fumas;
C>A because: 1% haste= 3% delay reduction, 2% DA better than 7 mere attack.
A>B because: 2% DA is +1.7% melee and +2.5% ws, so globally +2.2% damage. sword strap is +3.1% damage, difference is 0.9% damage, and 7 attack cannot beat that unless you never ws or something.
therefore C>B.
Inbefore uncaped accuracy.
uncaped accuracy? on a non HNM? really? If that's the case, with a 35% melee/65% ws split, hagun is +2~3% better than onimaru only ( not counting acc and attac bonuses). This is easilly beaten by 5 acc and 18 attack.
