....other than pork fat and olive oil

For those who do their own aircraft lubeing, which brand of MIL G-23827
Acft, Inst, Gear and Accuator Screw grease do you like? Why? any dislikes?

also for MIL G-3545 High temp/wheel bearing grease.

How old are these mil specs and have their been significant improvements
made in greases and should we consider a newer type grease??
