I know that I don’t have first hand experience with the H .
I bought a old school Q500 and did the camera upgrade to a 4 K on it .
As far as DJI stuff
I have had no update grief myself . But I know first hand that I can fly it a mile away and check my cattle from the air and I have 100% clear picture. I have flown it out to 3 miles over brush looking to find a lost calf and still had perfect picture quality .
There is good and bad with all brands . I only have 5 drones so i am limited on the tech with all brands .
Just fly and have fun .
