I'm on Android and use Castbox. Wouldn't recommend the free version unless you're extremely tolerant to ads. It comes with a good selection of other features (comments, recommendations, etc.) but I don't use them.
I'd also (tentatively) put PocketCasts forward. I switched to Castbox because I encountered an issue that made it unusable, but it doesn't seem like it was widespread when I was trying to find out what was wrong. Unfortunately the Support Team couldn't help so I had to leave it.
