They're dope! I have a Mavic Air and have gotten all kinds of shots I'd never be able to get before on it. I haven't used it much in a UE setting, because that stuff is mainly indoors, but I imagine if you find a big enough complex you can.
I'd say they're probably better for video right now (most new ones shoot 4k), as most top out at 12mp quality right now just for photos. I think the Mavic Pro 2 might be 24mp now though...
NOTE: There's a pretty intense learning curve to getting shots with them. But it's fun as hell.
