I've found that Insta360s require lots of post-processing around the seam between the two fisheye images. This is for indoor images, where parallax is a serious problem. I haven't tried the version that mounts two cameras on a drone which has the stitch line at the horizon.
I'll also note that the 360° equirectangular images I shoot with my
Mini 3 Pro are 18000 x 9000 pixels, which is bigger than the Insta360 image for even the latest camera.
This is the most important point. Safety and fun, in that order.
The only thing I'd add is that exploring new viewpoints of familiar places is one of the joys of flying a drone. (I view my drone as more of a 120 m tripod.)
OK, one more thing to add: don't discard images. Storage is cheap, and as your editing technique gets better you can reprocess old photos to produce better final images. I've reprocessed slides I shot in the 80s to good effect.
