Here are a couple I occasionally give an ear to:

Heavy Cardboard (https://heavycardboard.com/)
I listen to The Secret Cabal podcast and The Dice Tower podcast.
Occasionally a few others.
Fear the Boot (http://www.feartheboot.com/ftb/) for RPG's.
The Independent Characters (http://theindependentcharacters.com/blog/) for 40k.
Jaded Gamercast (https://jadedgamercast.com/) for non-GW miniatures games. Word of warning these guys are pretty salty, but I like them because they're from western Canada (Calgary and Edmonton).
For Age of Sigmar the two best are definitely: Heelanhammer (http://heelanhammer.com/) and Garagehammer (http://garagehammer.net/) - both former WHFB podcasts.
