Hi. Look, I think you could not say that one or the other cam is better in absolute terms. Each has its advantages and disadvantages. For me the main advantage of the Yi video quality is slightly above the GIT2 since the image is cleaner noise becomes especially noticeable in low light conditions. Also the possibility to optimize the maximum allowed by your hardware installation scripts allowing you to record at a higher rate than the GIT2 bitrate. Drawbacks of the Yi, a possibility that you come unfocused, has no rear screen and has no default stabilizer stabilizes although better than other action cams. The main advantages of the GIT2 are especially impressive stabilizer that brings, but to activate it somewhat reduced quality, powerful community and its updates lately but are lazy hehehe, the rear screen and its multiple configuration options. By car, it has more vivid colors and higher contrast than Yi. So now it depends on you what you consider most important factor. Greetings.
