I've had a similar experience.

I've never noticed a problem with Dropbox. Of course, I'm not running tools that show me battery consumption of apps and such on my Mac. Battery lasts long enough that it's never been a problem to look into.

I also had trouble with early versions of Google Drive. Maybe it's time to give it a try again. The problem I had was that drive thought all of my files had changed every day and started syncing the entire Google Drive folder again. I removed it and haven't tried it again since.

On my macbook pro Google Drive has improved but still causes trouble and generally runs much slower than dropbox, which has always run flawlessly.
