I think there is no answer to this question. A lot of them will have excellent service and as to which one is best is entirely up to individual experience. Also different customers will have different experience in a particular store.
Personally, I think 99% of the Hermes stores we've been to are very friendly, with the exception of 1 or 2 stores.
