I find it weird that you do not care for DE since it affects your workflow, but anyway.
My take is if you need the latest packages go for Arch if you have the time, Manjaro if you do not and finally Debian for rock solid stability.
I think it has some google libraries to integrate google drive and some other things(not sure). Personally I did not like the workflow. maybe because I am a Lawnchair user.
