Disclaimer: I am not a stab expert, just someone with some anecdotal experience
I am a big fan of the clear screw-in Durock stabs. I also just built a board with GMK screw-ins for the first time. I've heard people say they are not that amazing but honestly after clipping and lubing I'm very satisfied with them. I think Zeal stabs are going to be my next ones, after I use the pink everglides I ordered, as I hear absolutely glowing reviews of them regularly (which, I would damn well hope so, given how pricey they are).
As long as you are going to take the time to lube carefully and properly, I don't think you can really go wrong with Durock, GMK, or especially Zeal if you don't care about the money.
