And I like a blasted surface because it gets everywhere, especially in little nooks and crannies that nothing else can, and in seams, an important place for adhesion.

Glass Beads leave a surface you are referring too, crushed glass leaves a surface nearly identical to coal slag or sand. It is essentially the same as coal slag or sand when blasting. Leaves a really good tooth and gets steel "white". Been using 40/60 crushed glass for years. I think it's actually more aggressive than coal slag, it cuts quicker, removes rust faster, probably not as aggressive as sand but I never use sand because of the free silica in it.
All of what I'm referring too is in the context of blasting a body. Al OX would be prohibitively expensive to use completely on a body. At least for me. I will go through 15 or more 50lb bags of media when doing a body.
