I had always been under the impression that the extra resolving power of increased aperture only manifests once you start increasing magnification, but the other night I was comparing the 3rd quarter moon in my 8" SCT with my 12" dob, and even at the same magnification, the 12" dob was showing enormous amounts of detail and texture that was just invisible in the 8" (despite better optics in the 8"). In neither case was I pushing magnification to either scope's limits. Seeing was good, but not great.

Is that normal or were my eyes just playing tricks on me?
