This is a slightly complex discussion because the various English makers themselves have degrees of quality.
For example, Gaziano & Girling have their bespoke, then Optimum, also RTW and finally they had a made in Italy line as well.
EG has “top drawer” service along with RTW with the occasional makeups rebranded for other houses. (Ralph Lauren Purple Label)
CJ has handgrade and then RTW, but the also do rebranded shoes for the likes of George Cleverly…
So, this discussion has many and manifold nuances which factor in.
Now then, I own GG, EG, CJ and Church.
GG are hard to beat overall. EG as well. CJ are great for the money, perhaps CJ takes the “best value” prize. Church’s are far better than most give them credit for, and yet they are not as good as their past shoes were.
Overall, I favor GG. But they are very expensive and not easy to find discounted. I prefer GG for proper oxfords.
EG are wonderful smart/casual shoes but also do oxfords well.
CJ are sturdy and beautiful too. And can often be found deeply discounted…
All in all, you must try the various makers yourself and discern pros and cons accordingly. Cheers!
