Back when I was deciding what cloud drive to use I considered SkyDrive for a little while. However, after they admitted to the scanning of your files for nudes and illegal material I dropped them straight away and will never return. I've heard of the security issues with Dropbox so I always have any possible private/sensitive data encrypted in case the worst ever happened. (I use Dropbox because I have not found a alternative that just works)
