Both are cool. The visor seems more like what a security guard would have, and looks mroe robotic, less lifelike. The bug-eye mask, as I call it, was the first I saw (The first Oddworld game I played was AE, then AO.), and seems more like it gives the wearer an identity, and reeminds me of WW2 fighter pilot goggles. In my fic(s), I have the Sligs as a mixture of the two, most are bug-eye, but the higher ranked get the visors as they look more advanced and robotic.
