They’re basically the same phone. In fact, Redmagic is a sub-brand of ZTE. They only meaningful difference I’d say is Z70 Ultra has a telephoto camera which Redmagic 10 Pro doesn’t have. And Z70 has Wi-Fi 7 while Redmagic has “only” Wi-Fi 6. If you’re planning on keeping the phone for a longer period of time then this can help with the future-proofing. Online I’ve seen that Redmagic doesn’t have the best reputation when it comes to software updates, only offering 2. I don’t expect Nubia to do better on this front either.
