Not bad ratios on the 32T cassette, although you are missing the 15T and 17T on the Specialized. So it will depend a bit on which gear you settle into whether that would be an issue.
Cassette could be making
a little bit of difference. I know on flatter courses I have big "holes" in the 11-32T cassette. My preferred cadence puts me in the middle of two cogs, so I'm either spinning too fast or grinding too slow a cadence.
Potentially the 12-27T is keeping your cadence at a more natural and efficient level.
