Agreed, one can doo harm to seals with either device. Well sort of. The biggest issue is getting grease on brakes unless you totally over grease and pack the whole hub plumb full.
Actually for that system to work as designed, one MUST fill the hub plumb full.
You’re correct in that is what bearing buddy says. And in the past like 30 years ago, I thought that was the right answer. It also lead to grease always blowing past the seals.
I would never recommend someone filling the entire cavity with grease, nor should you.
I don’t believe there’s an exact science as to how much grease. But you sure want more than just 2 neatly packed bearings and a clean empty void between the bearings and you don’t want so much thst the spinning grease is continually in contact with the spindle. The right answer is somewhere in between.
I typically put a few good size globs in the void along with generously packed bearings. Guessing maybe total of about 1/3 full.
Totally full and bearing buddies is just a guarantee of grease getting pushed past the rear seal pretty quick once things heat up.
