I use Google drive, but the Linux support was awful and I started using insync. It's about $25 for a lifetime license and I love it. I run Ubuntu with encrypted home and have for years. It works great and I highly recommend it, and I don't work there, just a happy user. The Nautilus integration is decent too.
Not trying to rain on your parade, I hope it fills your use case.
However, my IT company onboarded a media-intense client with insync and it has been nothing but a nightmare. There are hardcoded limits (like only syncing two files at a time, IIRC) that make it effectively useless for anything beyond small, personal use. It's cheap and you get what you pay for.
I seldom use it, so I can't say how well it runs, but from Gnome version 3.22 if I'm not wrong, Google drive is integrated with Nautilus (the file manager) via GVfs/GIO and the couple of times I used it to share a file worked flawlessly.
