Hi PowerK! From my understanding. Multi-sampling offers quality on polygon edges. Transparency super-sampled, offers quality on transparent Alpha Test but doesn't touch transparent alpha blends -- do you have examples of it offering quality on specular artifacts? Specular aliasing is an ugly artifact. Full-scene helps reduce specular, shader, shimmering/temporal noise, shadow aliasing - to name some. Personally investigated the patterns of the modes and x4 multi-sampling and X4 SGSSAA offer x4 samples on polygon edges and x4 samples on textures. When in hybrid modes with SGSSAA, they offer unideal patterns -- for example x8 multi-sampling; the x4 SGSSAA positioning of the samples is not ideal like they are when the are matching samples -- that site that you offered is right on target.
