Please help narrow it down

I am so tempted to buy it, and if you guys said it was superior to the Viofo ai might, but at $100 less... if the Viofo is similar in quality, I‘ll probably go with that one.
thank you so much for taking the time to reply!!!!

I think you are really paying the extra for support if things go wrong, the build quality is not much different and the image quality is not much different either. If you value after sales support enough then go for the SG, if you value image quality then the Viofo.

128GB is a good size for a dual 1080 resolution camera. If you are going for a 4K resolution version then a 256GB is sensible.

1080 resolution is plenty to show what happened in an accident and remove blame, if you really want to capture number plates for hit and run incidents then a higher resolution camera can be very useful.
