Google Drive wasn't able to handle 30gb of storage a couple of years ago when I tried it. It was lagging insanely. I now have 700gb of storage so i'm a bit scared to give Google Drive another chance. Dropbox works very well. Also I don't like how Google Photos and Drive work together. If you edit a photo in Photos, it doesn't update the file in drive. I like to have all my photos as files.

OneDrive looks good, I'll definitely give it a try once my paid year of Dropbox is done.
