Depends on several factors, I used to have the original Mavic Pro which was a perfect size for carrying in the top box, plus the quality of the footage in 4K was superb. Personally I'd stick with a DJI as they are generally a known quantity, and I reckon you can't go too wrong with the Mavic Pro, or Mavic Air. If you aren't too bothered about 4K and are willing to sacrifice some other features then the Mini might be a good option. For me, shooting in 4K and having decent stablisation was worth the extra spend. Mine was £1300 brand new but you can pick some ridiculously good deals on the original Mavic Pro and Air. Just make sure you see it working before you buy, they are eye wateringly expensive to have fixed out of warranty, or even worse the first time you fly it you don't want it veering off and crashing.
