Finally new thread, after close to 200 pages

xiaomi no doubt

been using their action cam and dash cam

action cam use sony sensor, super clear
dashcam 1440 resolution, night time footage good coz aperture large enough

xiaoyi action cam

2k version, good enough for me coz the sony sensor good enough, but night time will suffer only

for xiaoyi dashcam, works great at night

4K definitely better than 2K version, with OIS
of course price way way way higher

hmm, couldn't really compare with digital camera as it cant zoom, focus and dont have much configuration
it is action cam, specialize to record point of view with its wide lens

if you plan to just record video, it does its work like a charm
