Agree C&J handgrades are terrific value. Furthermore, the maker has by and large resisted the temptation to introduce new "fashion forward" styles (the Truro trainer notwithstanding). For me, they excel at robust English classics, such as the Bradford captoe derby and the Pembroke full brogue. One caveat about C&J's lasts, however, which makes comparison with G&G difficult: they tend to favour a higher-instep, larger-volume foot. G&G's lasts are much sleeker and suit my shallow foot much better. I would also argue that G&G's manufacture (e.g. neatness and density of stitching) is a level above, even though I often find myself preferring C&J's quintessentially English styles.
Thank you for your observation about C&J v. G&G re: sleek lasts and high insteps. I am usually a UK 9E in C&J, although 9.5E in the Cranford 3, Weybridge and Chelsea 3. I found a pair of G&G (plain black Oxford) in a UK 10.5E at Last Call awhile ago and tried them on. They fit well everywhere except there was way too much room in the toe. Since I have anything but shallow feet, maybe I will never find a G&G that fits me. I feel confident that you saved me a $50 - $70 return postage cost.
