From a fee perspective, I have the Notary Cafe Pro membership and got one order previously (could not complete it due to a conflict). I have yet to complete my first loan signing, so there's that newbie aspect as well.
From a general user perspective, I prefer Notary Cafe to Notary Rotary. The forums are far more helpful, better designed, and more user-friendly than Notary Rotary's forum. The Notary Rotary interface is outdated.
As a note, I was also unable to refer to "Notary Cafe" in a comment that I left on that site - seems like they have certain competitor's phrases censored with their web programming. I was not particularly a fan of that type of censorship, as I felt it lacked taste.
Hope this helps,
