Curious as to why you don't like them. I have used them at my house on a couple of fans without any problems.
I've repaired a few ceiling fans that the homeowner thought was securely mounted to the joists, but in fact were just pushed up against the insulation. A few days later, they ripped down. I agree, solid blocking from joint to joist, provided you have the room to work in the attic. If not, check for obstructions or wiring, then check again, and then install the expanding ceiling fan hanger.
