Such as?

DJI Osmo cameras are good, I still have my original Osmo action and while the quality is a bit behind now, the battery life and general stability and menus are better than GoPro IMO.

I've found DJI cameras also don't discharge their batteries when sitting, my gopro 11 black is somehow always dead when I grab it even after a few weeks, but my osmo action is still at ~70% after a year.

Insta360 also has some neat offerings, but their software/app is absolutely abysmal, it's crammed full of ads and takes up several GB of space. It also requires an account login.
