Drone for Mapping?

[FrostBite]

 I am looking at upgrading my drone for mapping, but I'm not sure what I should be looking at.

Does the Mavic 3 Pro do well with mapping? I was interested in the portability of the drone.
Is the Phantom 4 Pro still good for mapping missions?

I was looking at the P4Pro RTK system. But I think that's out of my price range...

Thanks!
