Am bit confused between G8 and G9 Uni dex Sword of Warrior.....

I unable to figure out for which weapon shall I go as G8 provides: Decreases inflicted Damage by 5%
Ignores opponent’s Critical Hit Rate
While G9 provides: Decreases inflicted Damage by 7%
100% increase in attribute damage
Ignores opponent's Magical Evasion
as per the option I feel G8 is better as it will help against Archer but again I am unable to get wats Inflicted damage..
so guys please help me shall I go for G8 or G9???
