All but battery life: DJI action 2, I got mine on sale for 169 at amazon
I love this form factor and I hope they keep making something in it
It comes with a little necklace to wear under your shirt and then it just sticks to it magnetically, otherwise you'd need one of those 4 strap chest rigs to fit a bigger action camera
It does 140 mbit/s 4k120, but overheats, you could do lower framerates or resolutions for longer. Actually if you're not in a hot area the cooling effect from the wind might be enough to negate it. The sequels (action 3, 4, 5) each do lower bitrates. It's like what happened with the original eos M and it's sequels.
For my purposes (RC vehicles and also bike rides occasionally) it's perfect, everything else is too big or discontinued or too old. FPV drone guys are fond of it too.
I also considered the caddx walnut which looks like a slightly gimped version of it for only around $100 but it looks less available
