Thank you, everyone! It's very useful to get some second opinions.
@coldsalmon Yes, a black suit is not very versatile indeed. I suppose what I meant to say was that I prefer the brighter (petrol?) blue of the Napoli over the York, probably because it's clearly different from what I already have and from the standard navy that everyone else wears. And that the only disadvantage the Napoli has versus the York (or a navy suit in general) would be that it's not appropriate for funerals, but that it's ok because I already have a black (admittedly cheap) suit for that.
But then again I wanted a staple suit, and a staple suit either navy or charcoal. I just wish the York was a tiny bit more... blue. I might look at the Napoli navy for that, but it seems like less value than the $100 cheaper Napoli plain blue. The €259 Napolis are just absolute steals.
Sorry, I'm rambling, I'll just have to figure out what I want.
@bellyhungry While both suits pass the hug test and feel OK, the York definitely feels better and less restrictive, perhaps because of its wider chest? I get slightly more pulling at the shoulders with the Napoli when hugging and raising the arms. The pants of the York are also slightly better, but both pants will have to be tailored anyway.
Are you going to rotate the sleeve head? Might reduce the wrinkling.
