Okay, so you have a Typhoon H, a Typhoon H 'Pro', a Q500 and a Phantom 3, is this correct? Here is my take.
The Q500 is slow and cumbersome compared to all the others, moreover, while it is technically a 4K image it is not quite as good as the others.
The Typhoon H and H Pro are the same exact drone. Here in the states, the "Pro" label was given to the bundle that included the carry case, wizard wand, and two batteries. In addition it also had the ST-16 with three external antenna and the antennas in tubes on the aircraft while the 'standard Typhoon had the same antennas for the St-16 (3) - one was located inside the controller and it's aircraft simply had the antennas under a label on the sides of the aircraft. From a flying, operational and image standpoint - they are identical.
The Phantom 3 has fair imagery and 'sorta' compares to the Typhoon H - it is a good flyer but has all the downsides of the Phantom - gear and props can be seen in pics and videos while maneuvering and so forth.
If it were me? I'd ditch the Q500 and the Phantom 3 and keep - both Typhoons. Not long ago parts for these aircraft were getting hard to find, though there are now sources for some parts. Having 2 Typhoons with all components interchangeable gives you peace of mind should you need parts. The Typhoons most valuable asset is this forum. EVRYTHING about that system has been well understood and documented here in these pages. The Typhoon is a solid flyer and having the retractable gear and 360 degree panning camera give this aircraft (Typhoons), capabilities that no other brand has for anywhere near the cost.
On the downside - if you are new to drones the Typhoon may be like drinking from a fire hose; in that it is not forgiving to anyone who does not learn how to properly operate and maintain it, but as
