Depends I guess...
... when/where to use it? Where is the footage for? Budget?
I now have a GoPro HERO7 Black with some great stabilization options but using it on a helmet can be a challenge when you do not want to look like a fool.
Here it is mounted above the headlight (CBR1100XX) with a adhesive mount :
Here mounted on a crashbar (1200 Super Tenere):
Mounted on the steering wheel:
Helmet mount:
But you can do some really weird angles with a Insta360 ONE X:
