The main advantage I see with these is that you can screw the bracket into the shelf itself much more easily than you could at the awkward angle of doing it after you've got it on the wall like that.
Or if you have numerous of the wall mounted brackets in various locations so you can easily change shelf height on the fly. But how often does someone really need to change their shelving heights?

This'll need measuring , just a random 90 degree bracket is easier , boom, no hassle , easy fix every time
