In the video he actually mentions AntennaPod first too. Being a former Pocket Casts user for many years, I sometimes wonder if the reason people stick with PC over AP these days is primarily syncing, followed by maybe discoverability? Syncing isn’t really an issue for me as I only listen to podcasts on my phone. Discoverability isn’t as “robust” as PC but the most popular podcasts (at least according to Apple Podcasts) are easily accessible in AP.
PC made a number of UI/app logic changes and price changes over the last several years that just didn’t make me happy with the app.
One of the primary reasons I switched from PC to AP is because PC was pretty noticeable, particularly with a few specific daily podcasts, in the delay between a new episode being available and PC actually knowing about it and making it available. I believe it’s because they use a centralized service for refreshing podcasts versus just having the app use the direct RSS feed for the podcast. Regardless, I have very specific times for when I listen to podcasts based on my work schedule and having episodes not show up as soon as they are available even via a manual refresh just didn’t work with my use case very well.
