I don’t have a lot of experience with stabs, only ever got preinstalled ones in the beginning when I bought mostly prebuilt stuff, and durock ones after I got a bit of experience and started building my own keyboards.
What I can say is I am extremely happy with durock, especially if you buy foam stickers to place between the stab and the PCB, and if you lube them. Zero rattle, they feel solid, they look great.
