Good list. I'm also a HUGE fan of Antennapod [0], a podcast player app. It's simple, easy to use, and has built-in speed adjustment, so I can listen to some lower-information density channels at 2x speed.
If only it didn't regularly wipe all the data due to database corruption [1], with no ways of recovering and automatic backups. Until this fatal bug is fixed, I strongly advise against using this otherwise fine application.
I'm in the same boat - I've switched back to PocketCasts. It's sad, because not only is AntennaPod open source, but I think it's more featureful than many of the alternatives. But it's become unusable due to this bug.
I've gone over to SoundWaves, which is also on F-Droid.
I had a look, but I don't understand how it deals with 'new' podcasts. The play queue seems arbitrary and uneditable. But maybe I'm missing something. (Otherwise it does look nice.)
