Hello!
I don't think you will get an answer whicht of them is best. One prefers this dealer, the other prefers another one. But with the two you mentioned you can't do anything wrong, no matter which of them you choose. What I learnt here is that they both are outstanding.
(what I did: I ordered two watches about 2 weeks ago, one from Andrew and one from Josh, so I didn't have to choose but so far they didn't arrive, so I don't have yet an opinion which one I would prefer)
