DJI M3E vs P4RTK

[@RecoveryoneDrone]

both have mechanical shutters on the cameras, and when doing mapping colors are not that important compared to accuracy & precision of the flight. The Phantom 4RTK has its RTK built in compared to adding the cost of a RTK module for the Mavic 3 Enterprise series.

The batteries of the p4rtk are cheaper and they have extended batteries as well which I don't think you figured in. They appear to be the same drone effectively for commercial work imo, and the p4rtk can handle higher winds in practice and can be weatherproofed cheaply.

P4rtk still cheapest and best workhorse value for money on the market.
