I was looking for this comment. Hard agree. Every time I need some casual compositing tasks, or some transitions, Blender's never done me dirty. Every time I pull my head out of the ground and go hunting for another FOSS compositor, I always end up shrugging, "whelp, nothing really all
that better than Blender, and I know Blender, soooooo . . "
EDIT also, since last I used it, the Blender Compositor has gotten a lot better. Dang.
