296 hours myself. I have also been pleased with Overcast until just recently. Now that I am stuck at home, I went from listening to all my podcasts from my phone to listening to most of them from my computer. Overcast's lack of desktop app and pretty poor web interface are causing me to consider switching for the first time.
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.
