Prop question

I have an alumacraft yukon (16ft vee) and a honda 25 tiller.  I had the prop set up perfect, wot rpms, tilt ect.  Unfortunetly a rock has taken a chunk out of one of the blades (d**n thing must have jumped up from the bottom of the lake).  So new prop time.

Question is are aftermarket props any better then stock honda props?  Turning point with a hub is about the same price and I like the idea of being able to replace/change props at a lower cost.  Opinions????
