What podcast apps are people using these days

Hi,
I'm curious what podcast downloader people are using on their macs these days. I used to use downcast, but it seems to make my computer completely unusable and mute when it's checking for and downloading new episodes. I'm using a 2012 macbook pro with 4 gb ram and 500 gb hard drive and it's running 10.10.5. Any podcast app recommendations would be completely appreciated.
Thanks,
Moop
