Solution for Podcast syncing


I'm new to Apple products having recently bought a 13 inch Macbook Air. I'm generally happy with it, but there is one thing that slowly gets on my nerves and after extensive googling I can't find a solution.

I listen to a lot of podcasts. I listen to them on my Macbook, but also on Windows 8 and 7 PC's and my Nexus 4 and Nexus 7. Is there any solution which covers OSX, Windows and Android (the last one I can live without)?

Right now I'm using iTunes on Windows and OSX, but I'm flabbergasted by how awful of an experience it is. It's slow even on very fast machines, buggy, doesn't seem to sync across my computers. I've seen some pretty nice apps suggested for OSX, but they tend to be exclusive to Apple's ecosystem.

Had a look at DoubleTwist, but their Windows desktop app seems to be just for library syncing with your smartphone. Pocket Cast works nicely on Android devices, but offers no support for proper operating systems.

I guess I'm screwed because most podcast listeners care about mobile apps and proper desktop apps with syncing, libraries, etc. don't have enough demand for. Am I just SOL?
