Great comparison.
Actually the casebacks are bigger on the H Series gens versus the G's. My bottom line is that I am staying away from the newer reps until someone gets the crown guards right. On the H my guess (and it is a guess) is that the change in the clear casebacks is more pronounced than on the solid casebacks. I have owned both gens and reps of the earlier models and the differences are not nearly as pronounced. Yes, a gen is a gen and in a different league but PAM is also getting smarter. Better crown guards, engraving in between the lugs, changing the spelling on engraved bezels between 250 and 251, etc.
