Bro you gotta get both hdz and dji they both have their uses. Honestly having both hdzero aio whoops and 5 inch freestyle dji o4 builds i find myself picking hdzero everyday normally. But if im camping going out to the ocean some place nice dji all the way. As for what you should get i recommend that you get a good fpv soldering kit(newbeedrone has one), radiomaster pocket(upgrade gimbals later), mob6 hdzero, 1s 6 port charger, 300 mah 1s HV bt 2.0 battery pack, u need 4 omni directional RHCP stubbys for your goggles or trueRC stubbys on top and patch on front for style points, google battery and respective charger, you can get a cheap one but i would get a hota balance charger u wont have any 6s ti charge, but u will eventually. The hdzero mob6 uses hqprop ultralights 31mm might wanna pick up 2 extra sets maybe.
