I use and pay for DaVinci Resolve Studio on Linux myself, so yes I have tried them and yes, they're obviously more feature packed and polished than OpenShot is.

OpenShot is however significantly easier to use and does what you need for casual editing. If you want a step above that and still FLOSS then Kdenlive is a better choice.

What makes your original comment useless is that it reads like an American saying, 'I bet our GDP is bigger than Nauru's' - like what is the point? You know the answer already. An open source video editor is unlikely to be as good as DaVinci Resolve. DaVinci has multiplicity of the resources OpenShot/Kdenlive etc. do.

So again, what is your point?

At least we can agree in our mutual disdain towards american way of thinking *shaking hands*
