I haven’t tried Overcast in a few years. I checked it out when I was looking to move away from the increasingly buggy Downcast in 2016 but Marco didn’t support video podcasts and actually said at the time he wouldn’t so I ended up with PC.
Pocket Casts has a main screen showing all subscribed podcasts, either by list or icon (in your choice of sizes), shown in reverse order by new episode posted. Playlists can be color-coded and be extremely granular, and can be created under a number of categories like All podcasts, All episodes, Anytime, Duration, Downloaded, Media type, Starred. And then playlists can be sorted by newest, oldest, shortest, longest.
I subscribe to several dozen podcasts but don’t download new episodes for most of them deciding as they come in which I’ll listen to and archiving the undownloaded episode-item (which hides all old and listened-to episodes but can be seen and redownloaded with a click). So I’ll look at that main screen, see what’s new and triage. (Alternately, I could use a playlist of all new episodes, downloaded or not, and triage from there.)
My playlists include Sorted-by-length (so I can see short episodes to consume when I have limited time), New Releases, In Progress, Starred, All (sorted by newest first), and then categories like Tech, Cooking, Music, Outdoors, Lifehack, etc.
PC is supposed to have a nice Apple Watch app but I don’t have one yet so I can’t speak to that. And there’s an optional Plus subscription that give you synced access to a web app and file storage of something like 3Gb to upload your own audio, podcast-related or not. (Because I bought that years ago as a one-time charge I’m grandfathered into it, so I’m not really familiar with the specifics of that program.)
The Discover section is really well done, and shows podcasts by popularity, trending, by category, podcasts recommended by people in the podcast world (the ‘Guest List’), periodic highlights by podcasting group (currently it’s podcasts made by the CBC, and by region - it knows I’m in the US and shows me popular podcasts here, but I can also search worldwide, or in one of several different countries.
The one pain-point I have with Pocket Casts is when I have episodes from a podcast I no longer want to listen to but for which I have old downloaded episodes that are not a priority to listen to. PC doesn’t have the ability to stop checking for new episodes of a podcast - you’re either ‘subscribed’ or you’re not (and all old podcasts are deleted).
