Looking good, interesting comparison. As far as the Revell kit, information on the SMAKR site claims it is the Vista kit, also reboxed by Smer, which I have a copy of, and it does look very familiar. One way you can tell, is the Vista kit doesn't have any alignment pins as we know them, just a few very small tabs on the fuselage, and the panel lines aren't quite Matchbox trenches, but not Tamegawa fine either, more like the new mold Airfix.
