Which of the free choices do you like?
I only got 2 GBs. |(((I voted for pCloud. The software is very slick and works nicely. I think you get 10GB free which you can boost to 20GB by inviting friends etc.
I use the premium (paid) version but there is no difference except storage space.
They also offer client side encryption, but unfortunately at additional cost.
Amazon, too.Dropbox, Google, and OneDrive are here to stay. They are winners.
