I have two pairs each of Grenson Masterpieces (one on the 91 last, one on the 92) and C&J Handgrade (both on the 330 last). It appears to me that the production quality is similar. The C&J shoes fit me better than the Grenson shoes, but that's just because of the peculiarities of my feet. The punching on the brogueing on the Grenson shoes is sharper and more distinct than on the C&J shoes. C&J probably does a slightly better job at the antique finish on tan shoes. I don't like the full sock liner on the C&J shoes, and I haven't been pleased with the finishing of the heel pad in them. Neither make is equivalent to Edward Green, but they're both much cheaper. I would buy shoes from both makes again in the right pattern at the right price. A retailer's perspective might be completely different: it may, for example, that Grenson's lead time is unreasonably long or that a retailer has to return a relatively high proportion of shoes delivered as defective. I only know that I've been satisfied overall with each make (and Grenson Masterpieces, if ordered from Britain, are cheaper than C&J Handgrade).
