The DJI Media Maker program has shown it is superior for stitching panos over what the Spark can do.
However, it is not any good at vertical panos.

But, there is an answer. A free software program called Microsoft ICE (Image Compisite Editor)

Below are examples. One stitched in Media Maker and One in ICE. Notice the MM one is distorted badly.
Additionally, in the ICE program, you can manipulate the type of distortion in a pano and even almost eliminate it all together.
