I think it was more Leaf in general. I didn't have much experience with the brand when I wrote that, however I have much more now and the big points I make in that review still stand. Also in my articles where I discuss the Credo, which you can find on my website as well (both viewable here: http://brianhirschfeldphotography.com/?s=Credo&search=Search
) I discuss the Aptus series and some flaws which I (and others) see in these backs for certain applications.
If you are able to work with the AFI / Aptus software and UI (which I believe are the same but I am not sure since I have never used the AFI) then I don't think there would be any great trouble with the 10.
The MamiyaLeaf Credo is in many ways a baby PhaseOne IQ depending on what you are doing the Credo can be more economical, the IQ has some advantages including the focus mask which many who shoot on technical cameras find invaluable.
