With my above mentioned setup (MMF5 + Ortofon Super OM-10) CDs in my opinion seem to sound more detailed.
How do you have your MMF sited? What kind of rack, platforming, and mat are you using? A turntable is far more vulnerable to internal component noise, feedback, and room resonances than other electronic components because the cartridge is far more microphonic. Until I sorted out the platforming and turntable mat on my current rig (Technics SL 1210 M5G and either Ortofon OM 10 or Shure M97xE), I blamed a lack of inner detail on the cartridge. Isolating the turntable better and using a better mat revealed that either cartridge was plenty detailed for my taste. My CD player in the same rig is a Sony ES series CD/SACD player which was a big leap in detail over the CEC I had before. Yet, compared to the turntable, it's not so much the detail that I find so winning in the LP playback (though I don't find it lacking, either), it's the body of the sound and how it somehow communicates the emotion of the music better. Everything improved mightily when I put the turntable on a butcher block cutting board and put the cutting board on a set of Vibrapods. YMMV of course.
After doing some research, I couldn't find any reviews that raved about the OM20 stylus being much better.
There's a bit of buzz over the OM 20 and it's definitely perceived as an overachiever. See
http://www.furious.com/Perfect/vinyl48.html. Absolute Sound named the OM 20 and 30 (Super) both as Editor's Choice budget components, giving a slight subjective edge to the 20. See

Here are a couple of reviews at www.audioreview.com:
