You鈥檙e asking for opinions: for what it鈥檚 worth, I would pick either of the Explorer 2 models (but especially the polar one) over any of those Constellations and it鈥檚 not even a contest. Just my take, but those Omega models are unattractive to my eyes, and the Polar Explorer is one of the best looking watches in the Rolex lineup. I never used to like them until I saw one in the metal and then couldn鈥檛 stop thinking about it for a month.
Also, if you get the Rolex and change your mind, you鈥檒l be able to sell it for at least as much as you paid and probably more, whereas those Constellations will lose a ton of value the second you walk out the store (assuming you鈥檙e buying new).
But as mentioned, you鈥檙e comparing very different watches.
