I downloaded your two images, loaded into Photoshop and assigned the sRGB space to each. I then balanced the exposure using the neutral patches (they were about .1 stop different) and visually/numerically compared the two images. There is very little difference, I am now confused as to why you were disappointed.

I am sorry for not being clear, Richard! I did indeed use the Passport software, but was in the believe that it is basically the same as the DNG PE. I used both and couldn't notice any difference as to how the "profile" comes out. I didn't measure anything though. These two images are the final result, the "profiles" have been added to the image from which they have been created, nothing more (EDIT: I did the white balance again, after applying the newly created profile). I didn't measure the ColorChecker afterwards, I just had a look on the overall different "color cast". Just look at the paper on the floor, or the toys! The two cameras produce so different colors, that it is not possible to use them together like this. As we said, it would need further visual tweaking either in LR/ACR or DNG PE to make the two come closer. That's fairly easy, and is what I had to do. But the Passport, for me, does not work like advertised, meaning, bringing two cameras together. So I am trying to understand what I got wrong. Like things stand for now, there is no difference in using the x-rite colorchecker software or not, 'cause you'll have to tweak anyway. Tweaking right away just safes time. Or maybe not, because it helps to get the values closer, and tweak from there. But then everyone should/must use the DNG Profile Editor together with this product. In fact they should ship together... I hope I could explain myself a bit better.
As a side note: Why did I try the Colorchecker software(s) at all? Because I regularly want to check results against my actual workflow, which is via ICC profiles. That way, IMO the two cameras come easily close enough to be used together. provided you take maximum care on how you shoot the target (one light only in the black) and which target (gloss, natural pigments and a lot of patches if for LUT based profile).
