It's also good enough for most people who'd like to share some videos on Bitchute or YouTube or some other site like that.

For hobbyist purposes like editing a short video from video clips taken with your phone it's fine. It's just not up to par with Adobe Premiere Pro. You will find kdenlive lacking if you are a professional video editor. Today that is no longer true The latest versions of kdenlive you get shipped with distributions (that would be 18.xx.x or 19.xx.x) are solid enough.

It wasn't usable until around 2010 and it was still buggy in 2015. Kdenlive has historically been ridden with bugs and calling it 'a buggy pile of crap' was entirely accurate for years and years. It is hands down the best choice among the free video editors available. Kdenlive is a timeline video editor built on the KDE and MLT frameworks. The second best is Shotcut and there's also Flowblade which is not nearly as good as the other two but works. The best free software video editor for Linux systems is kdenlive.
