Rear View Mirror Dashcam or Stand alone?

Hi guys, I have no experience in using a dashcam. I think it’s about time to buy one for my car haha.

Ano po tingin niyo mas better in terms of efficiency and quality, yung built in na dashcam sa rear view mirror (touchscreen) like QCY and EST or yung stand alone like 70mai and DDPAI?

Also any model recommendations? - with night vision - recording kahit nakapark
