File one epub size: 6.4 MB
Kindlegen mobi: 8.1 MB
KP mobi: 8.6
KDP mobi (the mobi I downloaded from Kdp to test it): 8.6

File two epub size: 1.0 (this is the one I originally posted about)
Kindlegen mobi: 2.5MB (not 1.0)
KP mobi: 2.7
KDP mobi: 2.7

So KP does produce a slightly larger mobi than Kindlegen. I checked all my old ebooks and they're totally functional. I'm still a little curious about the slight file size difference if you want to venture a guess, and I assume it would be safest to go the KP route from now. Would you agree?
You could run kindleunpack -d on the various mobi files and compare the assembled_text.dat files in the difference viewer of your choice.
