Synching with GDrive for me has been painfully slow. I thought it would be a drop-in replacement for Dropbox, but deleting files in particular seemed to take forever. Probably just some growing pains, but I've never experienced that with Dropbox.
EDIT
Also I had an issue with my mac pinwheeling google's 'Backup and Sync' agent. It's fixed now after a couple months, but there was nowhere I could find to report the problem to Google.
