From what I gather, the screens function generally the same, but display differently, though that's mainly just a matter of what you get used to. The biggest difference appears, at least to me, to be what the systems interface with, and how. AFS seems to have more flexibility with third-party equipment, but the Skyview integrates with less trouble since it's limited mostly to Dynon equipment. I understand the AFS has more serial ports, which will matter to some.
