The Royal Oak Offshores are unfortunately too big for my slender wrist, and I think their faces are a bit too busy for my tastes. I bought a 36 mm model for myself. Of note, though, I do find the crown design a bit tricky and fussy to operate. For a stainless steel case, they are also kinda pricey, but my little watch collection would not be complete without a Royal Oak...
This summarizes why I would choose the Royal Oak (and which one) from among your choices. But why go with any of them? I mean this sincerely. By my way of thinking, watches are either dress watches or tool watches. There are many dress watches that I covet. But the watches you listed are all what I think of as sport or tool watches. As a tool watche, I have been using a quartz TAG-Heuer for nearly twenty years as my go-to watch when I need absolute reliability or when I just want to not fuss with my watch for a month or two at a time. Over the years, it has served in extreme circumstances, exactly as a tool watch should, with the worst effect coming from some high altitide and cold-related leakage (moisture spotting on the dial). I would not rely on any of the watched you named for that purpose, and if they can't be trusted, then I don't see their value. I have several Speedmasters (two cal. 321s and the 125 Anniversary model) and they are interesting, but I would never trust them as I would my Heuer. I wouldn't even trust my Thommen Airspeed, which is a modern automatic. Nor would I trust any of the watches you listed. Everything in my TAG-Heuer but the case has been replaced during servicing, which is probably why it has been so reliable, but at the last service, I was told parts were no longer available. At some point, I will need to replace it, and its replacement will be a Rolex. Perhaps my trust in Rolex is misplaced, or the watches you named are equally reliable, but I just don't see their value.
On the other hand, with the exception of Panerai, most of those makers have other models I would be thrilled to own.
