I agree with this assessment. I like Vass and have several pairs, but I consider them my "rugged" shoes and boots based on the stiffness of leather. For G&G, I think that you are paying for the elegance of their lasts and the variety of RTW styles you can find at the numerous retailers.
In my opinion, buying Vass retail in the US is not a great deal. If that is your basis, you may was well jump up to G&G.
Also, if you study the nail patterns of G&G, EG, CJ etc, you can probably tell which RLPL shoes are from which maker.
A final thought - Saint Crispin's is not a huge jump from G&G, and Skoak is now offering trial shoes for sizing. That would take the sizing risk out of the picture.
