FWIW, i've been using Insync on Linux since it went online (because Google never released a Linux-native client). Aside from one massive screw-up on their part about 8 or 10 years ago (where they automatically converted all of my 100+ gdocs-format files to MS office and deleted the originals), i've not had any issues with them. (In that one particular case the deleted gdocs were all in the trash bin, so could be recovered. Nothing was lost, it was just a huge pain in the butt.)
