Hogue overmold for me. It feels thinner than the MOE style to me (replaced the stock MOE with one actually) and that was what I liked about it aside of the standard Hogue texture. I did get the beavertail on both the the Hogues that I have because I liked that part of my old MOE grip.

Cousin got the STI Scorpion I think it was. Not for me. Hard front side with a squishy rubber back side. Its almost like a wad of gum back there. If you hold the rifle in one hand and just twist your wrist back and forth it flexes from side to side like nobody's business.
