Royal Oak 15450ST durability vs Rolex 36 WG Day Date

[dexvd]

I've heard that the bezels of the Royal Oaks can be scratch magnets but as compared to the Rolex they are steel as compared to the softer white gold, so I'm thinking the Day date may be just as bad or worse for showing signs of wear after day to day wearing over the course of years.
I understand the Day Date has more water resistance but I don't intend to swim or play tennis or golf with the watch on for that matter, so I'm thinking the 50m of the Royal Oak would be sufficient for hand washing, being in the rain, etc.
Rolex are known for rock solid construction, are the issues with the crown and stem breaking on Royal Oaks not present in the newer movement of the 15450?

Any thoughts on this comparison? Both have beautiful bracelets and the pre-owned market for the 18239 and 15450ST are similar. They both seem pretty versatile for wearing with polo and shorts up to a suit.... I have plenty of other watches (Rolex and Omega) that are more sporty and more casual but I guess I am looking to have a "main watch" or "grail watch" that I always want to reach for regardless of the day or what I am wearing and while I'm not intending to use it for spelunking, something durable enough to not look beat 5 years into ownership.
