42" Husqvarna and "Factory Original" mulching kits comparison

Comparing mulching kits from Home Depot and Lowe's

I used these blades ALL YEAR 2017, no bags, no side discharge, grass is super healthy and thick, surprised...

[@Johnny53kgb-nsa]

Are these high lift blades or mulching blades?

[@ureasmith3049]

I find the OEM mulching blades cheaper to buy online, even after shipping factored in.

[@dalejacobson7442]

Is one brand harder (stay sharp longer), than the other?

[@johnanderson1149]

They seem to be identical except for the color. I'd think that no, it probably won't make a difference .
