I've been using the Amsoil grease for quite some time now. The real evidence of how well it works is that I haven't had to replace a joint in any of my forklifts since beginning to use it. My lifts have to travel through a dirt/rock/pothole/mud field, and routinely sound like they are getting thrown down a chute, rather than travelling over level ground when they are moving over that nasty terrain.
Of the three greases you mentioned, all are superior. I've just had the best experience with Amsoil.
