For a while, I had Google Drive and Dropbox. That was when Gdrive was $5 for 100GB, and that price couldn't make me switch.
Seriously, Gdrive does not measure up to Dropbox. The Dropbox client is so, SO much lighter on system resources than the Gdrive client, it's stupid. I've had Gdrive end up sitting on 300+Mb of data while Dropbox happily ran with 50Mb.
As well, Google Drive has exactly one mode: on. There is next to no configuration, which led to some humorous situations.
At one point, I took down all the bandwidth at a Hackathon because Gdrive wanted to sync a bunch of files, and there's no way to limit network activity.
I do not like Gdrive, and honestly I don't feel like I need it. Their main selling point is cheapness, but my working data-footprint is only about 40GB, which fits nicely within my Dropbox account (and on my very small SSD's). I don't need, nor could I use 1TB of online space.
