Once you determine you need silicone, the next step is viscosity. A product that tries to be a dielectric grease and brake grease too, compromises on both.
Get the 3M for brakes and bushings, and something like Permatex 22058 dielectric for electrical apps. If you use the right grease you don't waste any and decrease maintenance.
You shouldn't need to reapply 3M grease often enough to need grease jerks. That's more often needed when people use the wrong lube so they have to keep reapplying it. Maybe if this is a racing application but in that case I think you'd want to replace bushings more often.
Ironically, I could easier see someone skimping on oil when it's just going to replaced every few thousand miles than skimping on lube when it costs less, much less considering how long an 8oz container of 3M would last the average person.
If you just want me to say buy a cartridge of whatever, you can do that without anyone's approval. Those are not "bad" per se, but if you're only buying based on cost and not the viscosity relative to the application... one size fits all things, rarely do best at anything they do.
