MEGA is similar to SpiderOak because it claims to encrypt your files locally before upload and not have the keys to decrypt them ("zero-knowledge"). However, since its inception, MEGA has been mired in various controversies and has had security flaws detected (since fixed). SO has enjoyed a solid reputation. Both MEGA and SO can become slow when dealing with large numbers of files (not necessarily large files).
