8 3/4 rears summit or dr diff

I am in need of rear brakes due to a bad transaction on here for the rear end I bought. Dr dr diff has a lot of following here but are priced a lot higher than the summits and even some wilwood kits just wondering what would be the best kit and why trying to stay on the cheaper side but if dr diff is the go to then I will get them. Thanks
In my experience and opinion I would stay away from the GM calipers with the built in e-brake. They were a PIA when those cars were new and they haven't got any better no matter who sells them.
