Edges do seem a bit easier..
I don't think so. Corners are always outer layers, but edges have a slice move somewhere, and there are more opportunities, which in my eyes makes it harder. Also, it's confusing that there are M'U2MU2 variants that makes the not centersafe optimal solutions between 4-10 moves. And then there are <RU> algorithms like U-perms, that aren't move optimal but speedoptimal.
