I've tried exactly once (given that I know blender anyway and no video editor), and ran into audio sync issues at export that didn't happen when playing the timeline from blender. There were some mentions of the issues on forums, but no purported solution worked.
The gist of it is that Blender is not a video editor, but a highly capable 3d kitchen sink containing so many features that, in combination, mean that you can use it to edit videos, outranked in its own area of expertise only by Houdini. There was never a real push to make it particularly good at video editing, and unlike in other areas it didn't happen by accident, either (Blender is e.g. arguably the best 2d vector editor ever since it got grease pencil).
