I just bought the Pro after going through the same "Zoom vs. Pro" analysis. In the end, it was a very easy decision because I could only come up with a few scenarios where the Zoom created a better result.
Here are the only reasons to get the Zoom, other than the $200 price difference:
1. Dolly Zoom. This Hitchcock effect wasn't even that great when he did it in Vertigo and Psycho. It's a gimmick. Not needed.
2. Fast Zoom. This is probably the only reason you'd want the Zoom, namely when you want to have a shot where the zoom happens really, really fast. For other types of Zoom, you just fly the drone closer and, in Sport mode, you can get close to something pretty quickly.
3. True optical close up. If you want to get a shot that is cropped more closely you can do that optically with the Zoom, but have to use the HQ mode on the Pro. Since the HQ (zoomed in) mode on the Pro actually produces a sharper picture (long story about the lousy in-camera downsampling in the Pro's wide mode), and since the Pro's camera is so much better, I see zero advantage to the zoom.
So for me, it came down to one feature, Fast Zoom, and that for me was amazingly minor compared to the manual control over aperture, ISO, & shutter speed; shallower depth of field from a 1" sensor (as well as being able to force full wide-open aperture); better lens; broader range of filters; and much more.
