Yeah, I've never had a good experience with the Google Drive client. Heck, I remember when the Windows version would suck up all available file handles and basically make the machine unusable.
That being said, the whole point of Dropbox to me is that its cross-platform. iCloud Drive is basically worthless for the Dropbox use case unless your entire computing universe is on Apple equipment.
Funny enough just yesterday they announced a completely redone Windows client that they built collaboratively with Microsoft to use the right APIs etc. There’s a bunch of news chatter about it right now.
