I use Fountain now, but for a while I used Podverse. Features I like in Fountain are:

1. Value-for-value sats streaming and boosts

2. I like the way the queue works, letting me organize what I want to listen to next.

3. The activity feed on the home page is interesting, although I should look at it more.

There are several podcasts I like, but for here I recommend the Thank God for Nostr podcast.
