I think it's too early to tell with Yuneec when it comes to things like the FC. This is very much a new platform, and things like the RealSense seem to mean that they've had to do a whole load of development that 'plain' flight controllers just don't have to worry about - Yuneec are a member of the DroneCode group, but it's clear that the H code base has been changing very rapidly for the last few months. The ball is very much in Yuneec's court at the moment when it comes to third party integration, but I'm optimistic that they will see the benefit of working with others - just as DJI and others have done.
Things like the 360 gimbal start to matter when you integrate obstacle avoidance and smart navigation because the drone should be facing in direction of flight to take advantage of the additional sensors. The Phantom (and Mavic) have a real problem that all of their smart sensors face the wrong way if the subject they're filming is not 'ahead' of them. Their demo videos hide it well, but basically all of the follow me/watch me modes on DJI products are only good for following behind a moving target. The Yuneec follow me/watch me modes are quite happy to film from the side or ahead of the 'target' whilst still avoiding obstacles, and maintaining a constant bearing from the thing being followed. DJI do have a 'follow from in front' mode (I understand you have to check a box to make it work), but even that tends to end up following from behind.
Unfortunately, things like that don't show up in quick test videos - people try out the follow me modes and don't really think about how they'd use them for real filming.
@PatR I think you underestimate the value of consumer drones. If you consider that the H includes a 4K camera, 360 degree gimbal, hex copter, R/C unit, 7" android tablet and charger and batteries, along with all of the complex software integration to make them all work together, the price they charge is not bad. Sure you could get a cheap Chineese 4K camera and tablet for a nice low price, but they come with no software, no support and seriously low quality. My father in law worked for years in China in this area and the difference between 'cheap but ok' and 'decent quality' is huge. I showed him the H and he was very impressed with how much has gone into it.
