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've found him pretty consistently unwatchable tbh.

He sometimes covers interesting stuff, but the style/etc rubs me wrong.

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.
