I haven't tried the blender video editor, but Kdenlive has gone a looong way from the crash-all-the-time days to a modern and intuitive video editor (for a hobbyist at least).
Unfortunately on my xenial it still crashes so often that it's basically useless. I had to put together a short video recently and, after checking out all the available options, I ended up using the free version of Lightworks. I didn't try Blender though.
Tried kdenlive just a couple of days ago and on Ubuntu 16.04, it's as crash-happy as ever
kdenlive is awesome. its not perfect and it can be a bit quirky but for foss I love having it for quick little videos.
