Conclusion
Both cameras offer brilliant 4K footage and are very simple to use. But ultimately it comes down to a trade off of size v's recording time.
I want the smallest and lightest option.
If you want a camera that is so small and light that you barely notice it's there, the Insta360 Go 3S is the best choice. However a small/light camera means limited battery capacity so if you want to record more than 30mins you'll need to purchase the add on battery base. However most track day sessions or grass roots level races usually only go for 15-20mins so the Go3S is perfect for the this applications.
I need to record for longer periods.
You have two choices. Insta360 Go3S with the add on battery base or the larger DJI Osmo Nano. Both solutions are bigger than the Go3S on its own but if you want to record for longer periods you don't have any other options. Keep in mind both solutions are still half the size and weight of a GoPro!
