VXDIAG NANO vs VCM II, Which better?

Recently, many complained their confusion to buy a diagnostic tool for Ford or Mazda, for there is a full chip high quality VCM II for nearly 180$ (SP177-C) and there is the new VXDIAG VCX NANO for only about 100$. The price difference is ridiculous and sellers claim they both do the same thing.

*similarity:
clone vcm 2 & original vxdiag come with the same software--> thus the same function & vehicle coverage & language support & O/S requirement

*difference:
vcm ii - clone vs. vxdiag - original (different factories--> different brands&firmware--> different price: vxdiag usually cheaper)
different drivers
