I used to use Litchi when I owned a Mavic Pro, but I lost it and now I'm looking at getting a Mini 4 Pro that can'tuse Litchi. So I'd like to know: are there things Litchi can do that DJI Waypoints can't? For instance, I loved the way you could get Litchi to follow the terrain by choosing 'height above ground' rather than 'height above starting point'. So are there any major differences, and does Litchi still win out?
 
Yes, there are a number of differences. Some major and some minor.

Arguably, the single most important difference is that Litchi includes their Mission Hub. The Mission Hub provides a way to interactively configure missions using the large screen and comfort of your desktop computer. With this system one can even simulate the flight in Google Earth Pro prior to flying it with a drone. Using DJI waypoints, one is constrained to using the screen of the flying device which is often much smaller than a desktop monitor.

Another important difference is how both Litchi and DJI create a flight path defined by waypoints. With Litchi, the waypoints define the bounding box of the mission where the flight path does not necessarily pass through the waypoints. With DJI, the flight path does pass through each waypoint. Initially, one may thing that having the flight path pass through each waypoint makes more sense. However, having the waypoints define the bounding box of the mission has advantages. There have been cases where people have designed missions using the DJI platform only to find that the resulting flight path passes closer to the ground than any of the waypoints (outside of the bounding box) which can result in a crash. More details about the difference in flight paths can be found here:


As you mentioned, another feature of Litchi is the ability to specify the above-ground height (as opposed to the above take-off height). To do this, Litchi uses elevation data to convert the specified above-ground height into above take-off heights used in the drone.

There are other difference relating to "waypoint actions" where Litchi provides a bit more flexibility than DJI Fly.

I have created a suite of utilities that extend the capabilities of Litchi. One of those utilities can be used to convert a Litchi mission into one compatible with DJI Fly for your Mini 4 Pro. This way, you can continue to use the superior Litchi Mission Hub to plan your mission but then convert it into a mission for your Mini 4 Pro.
