I don't love its web interface. But its ability to do the smartspeed thing + sync the played status to my phone for when I move from my desk to walking the dogs has been enough to stave off the switch for me.
I haven't yet spent much time researching alternatives. One podcast I used to listen to is now a Spotify exclusive. I use that to stream music and I really like how their desktop and mobile apps work together. I was thinking of giving them a try for podcasts until I realized it didn't seem possible to import an RSS feed. That would eliminate the ability to listen to Patreon supported podcasts which is a deal breaker for me.
What are you thinking about switching to?
