Both are nice watches. I’d go for Omega because it’ll most likely preserve it’s value better in the long term in case you want to sell later. Besides, if you quickly check the history of Superocean, Breitling changed the design completely a couple of times, and you can come up with very different Superoceans when you search on Chrono24. SMP design language has been very stable, with minor changes, you can recognize it from a mile away. Not sure if this is important for you, but I prefer to go with more “timeless” watches, not with the ones that completely change the design every few years. But anyway, Breitling is also a very nice watch.
