I think a better comparison would be to Windows Movie Maker or iMovie. It is ridiculously easy to use, but I don't think it has the work flow of professional editing software.

I used it a few times to make simple compilation videos - every year I teach a summer camp for kids, and I collect videos throughout the week, put them together and add a song which the kids choose. All I need are just a few transitions, and ability to add titles. With Openshot it was simple.

One year I used Adobe premiere, and it was like shooting a mouse with a bazooka. A lot of time and effort, for just basic stuff.
