since I don't have the luck to have handled any of them, but judging from spec and picture I'd pick 5207 with it technically superior instantaneous date changes and I particular like the apertures' legible layout! The serrations on the case doesn't add much for me but case's not so much a deal breaker!
Oddly, I don't find the retrograde date appearing, so the beauty of 5016 was not to my taste. FYI I've turned down a 5159 and went for a 5960 when they were offered at the same price!
