Opinion about new German Podcast

I’ve started four Podcast Series in German and I want to know, which you like best, because transcription is a very hard work. I will prefer transcipting the podcast that you want to here. There are a lot of parts of each podcast. The Podcast Series are:
Wanhoffs wunderbare Welt der Wissenschaft
Dübels Geistesblitz
Gans am Boden
Der NABU-Podcast
