Actually, the VisualEditor is the buggiest overall. However, GoosebumpsArt is correct in that the most recent issue with mysteriously inserted empty lines was related to the rich-text-editor. Personally, I use source editor as it is the least buggy of the three. This is not to be confused with either VisualEditor's source mode or the rich-text-editor's source mode; both of which provide a similar experience but are still a different editor.
