Thunderf00t covers interesting topics, but last I checked his editing style was extremely obnoxious with large segments - sometimes 80%-90% - of new videos being a retelling of other videos (and too often one about Anita Sarkeesian for no reason).

Did he improve at all?

I think he's good as long as you can remain critical - he's brings up some good topics but people need to come to their own conclusions. He's pretty anti-SpaceX, but I think some of his criticisms are off there.

I remember one of his arguments was that starship was nothing special because fully-reusable launch vehicles had already been tested - but who cares about that? On the other hand, his criticism of musk's vegas tunnel is fairly spot-on IMO.

Hmmm.. seen this recommended a few posts on this thread, but just browsing through the channel and it seems to be mostly Elon Musk hate videos.
