In May, I made the choice based on my experience with MP4 on my two channel camera and to distinguish it from video files from other camera. Never used used MOV before and I am glad I selected that format. In the version I downloaded in May, I assumed all three file formats did the 1 minute overlap as there wasn't that sub window.
If I have a choice, I would avoid using MP4 formats on my dashcams as it can not easily concatenate (merge) several files into one unlike avi. If I have several small files regarding an incident, I would like to group them together without going to an editor on my Linux box.
Works
Doesn't work
There are headers in mp4 that therefore prevents successive files from being merged together in Linux at the command line unless you use an editor.
Now there are some ways around that

Given that mobius makes clip at a minimum 3 minutes, unlike my two channel that does 30 second clips, this isn't a big deal.
I never have tried
as the 1 second overlap needs to be manually edited out. Usually I only need 10 to 50 seconds from a clip. Only twice did I produce a project where the incident was on two different REC files.
This could be an issue if you have three or more files on the same event that you want to combine. I do plan on making a script that removes the 1 second clip at the end if there are successive files.
Now with MP4, I have noticed a 1 in 50 chance on my two channel dash cam, that there could be a half second or more missed as it goes to the next successive video clip. My wife had to brake abruptly on a near head on collision a car heading towards her on a narrow street with double parked cars. About a second was missing
Given my experience with MP4's and the software's acknowledgement with AVI's - I will stick with MOV.
