Google Drive is working fine with me and I believe that it is way better than Dropbox. I'm also using Chrome in order to access my files and it works fine. Google Drives also enables you to access and sync your files in your desktop you can see the procedure here as well as the comparison of Dropbox and Google Drive:

With that comparison I do believe that Google Drive is really way better. Maybe Google Drive is just encountering problems during the time when you are uploading your files.
