I've tested the new Nikon Black 4k and Leupold RX-2800 and I think they're both great options. The 4k definitely has more range, in fact, I was able to get 2400 on trees and 2800 on rocks. A friend of mine was able to get 3400 on a water tank, but neither of us has been able to find any animals to range past 1200 yet. I really like the built-in features of the Leupold with the W/DNA, but if you don't need that data, then I'd probably save a little money and buy the Nikon. Also, if you don't need quite the ranges that I mentioned, the Nikon 3000 Stabilized is pretty impressive. I didn't think that I would need image stabilization as much as I did, but it certainly helps at over 1,000 yards. Good luck!
