To sum it up, and take with a grain of salt. JF V7 nice dial, JF V10 proper internal bezel, Can't put a V7 dial into a V10 cause lume won't match, ZF probably the best overall cause internal bezel is pretty good and date font and cyclops is "better" than JF V10
ZF rubber strap isn't as good as JF
Honestly, to me the JFV10 and the ZF both look great, you have to really nitpicky to worry about the differences, if you want to know more or double check this info you need to read a whole lotta pages.
