For what I've been reading, the Rylo's video capabilities are very good, mostly its stabilization. They just released a software update that allows for filming 180 instead of 360 in order to increase resolution. Sounds interesting. Also read comments about the stills not being as good as the ones from a Ricoh Theta S (which I own) but the company is also releasing some software updates for it. However, I still need to "find" $500 in my budget to get one.I've seen that camera. It's pretty interesting but you can't control it from the controller or from far away... I guess you could pick your shots in post but I'm also suspicious of the video quality. Casey did a review on it and wasn't overly impressed if I'm not mistaken.
I hear you on NFZs but I swear I have never been prevented from flying anywhere that I've wanted to by DJI. I'm actually appreciating the system because it has warned me of helipads and unpaved airports around me that I wouldn't have known about otherwise. I like that it keeps me abreast of possible hazards while I'm flying. As with anything, you can focus on the negative or the positive. I don't doubt that there have been bugs but DJI constantly updates the system and you are capable of submitting any false NFZs to them for review.
As far as NFZs, I'd rather be the one deciding instead of missing an opportunity because of a bug. You that thing about Murphy's Law. ;-)
