i disagree, flying the route first rather than just points on a map is a good thing really, POI works substantially better than my Wookong M machine ever did, dont get me wrong there, it worked ok, but the H`s is far better imho, also it does not suffer the dreaded dodgy vertical descent problems the Q500`s suffer from, with the H, you can come down quite fast vertically and its spot on, manual landings are also smooth as silk, one thing i will say after owning a few DJI equipped Multis, and still do fly them, the Yuneec GPS position hold is a lot better, on the H even more so imho, its literally glued in one place, allowing no issue at all with sorting the camera out.
End of the day though, you said it yourself, they all have their possible problems, so in effect your answering your own question really, they either go belly up or they dont..
have flown Quads for so many years now,,i needed a change, but with never having any major issues with my Q500+ , rather than build a Hex, i decided to wait for the H release, and very happy i did.
as for the realsense...granted "some" will use it, most will only "play" with it and a few will never ever use it...and like the advertising videos..many of us will never be able to do that due to rules, guidelines etc..if you take any notice of them anyway.
you can buy the IPS unit separately, which allows flying indoors ( when released ) , so i may plump for that, over the front facing realsense, as i can never see myself requiring that avoidance at all.
The ST16 is great, feels well built, does not feel cheap, and everything works nicely on there, at first after being used to a normal sized TX for lots of years, i had my doubts about the sticks being so far apart...unwarranted though, it actually feels more comfortable.
