I have used blender but for my purposes (simple, my skill level does not permit complex graphics) there are others I use. Kino, PiTiVi, and avidemux I have used and like.
I have been using 'OpenShot' to create the montage music videos on my youTube page... I use avidemux to cut and transcode existing videos (I don't think it qualifies as a full-featured video editor). I have looked at PiTiVi also...
