Very much this. I was using Dropbox, and the 2 gig free plan wasn't enough, but I sure as hell didn't need a whopping 1 TB, so I switched to Google Drive. The 15 gig free plan is enough for me, and I can rest easy knowing that if I end up needing only a little more, I can get 100 gig for $2.
That said, I definitely preferred Dropbox's client more. Google Drive for some reason is frequently showing an X on it's sync folder indicating it isn't syncing even though it's working fine. Google Drive's client also seems to be really slow to start.
