I've stopped listening to Kvack! too. I like the people, and I enjoy listening to them hanging out, but in the limited time I have and the massive amount of content out there, that's not enough to put the podcast in the queue. It's too much opinion and too little education and insightful analysis.

I quite like https://theesp.eu/ as well, but it's also far from SGU levels in relevance and production values. Unfair perhaps, as SGU has over a decade of podcasting under their belt, but that's how it is.
