Hi all, I currently have the spark... it is pretty good but I am looking to upgrade. Any suggestions? Mavic? Phantom? Or should I wait? Looking for 4k...

The Phantom though it is bigger is more sturdy in flight and deals well with the wind... the Mavic is also great because of its small size but it all comes down to a trade off in the end, so you might give up one thing for another.

Mavic air of course

The Mavic series could be the right answer as DJI have stopped the phantom line

And there are some news out there showing leaks of the new Mavic Mini, if you are not in rush maybe you can wait for this one

mavic easily. I will never buy a big drone again. I use my Mavic a million times more then I did my phantom just because of the size and how quick it is to launch.

Upgraded from Spark to Mavic Air. Best choice I ever made.

I will suggest you Mavic pro it is available on Amazone store to let me share the link of the which helps me to buy the Mavic pro  
I can not share the link here because of forum policy terms but you can visit gadgetspath.com

I have sure enjoyed my Mavic2 and it is very easy to fly. So far it is much more than I need or use.

i have a Freefly Alta 8/ MoviPro Complete Aerial Cinema Kit  for sell

go for the mavik.

I'm a phantom 4 pro v2.0 user. Can have my drone in the air within 5 minutes, fast enough for me. Camera is better on this than the mavik. Do some research, Google is your friend.
