FX and FXX have different programming. Right now both channels are mostly filled with a few shows before the new Fall season begins. FX is mostly airing shows like Kenny vs Spenny, Murdoch Mysteries, Modern Family, The Simpsons and past seasons of American Horror Story. FXX is airing stuff like Brooklyn Nine-Nine, Hudson & Rex, It's Always Sunny in Philadelphia and Family Guy. If you have the Gateway system you could always just go to the " Channel Listings " in the Settings section, add both channels ( here in Vancouver the HD version of FXX is on 265 and the HD version of FX is on 267 ) and then check out the listings for yourself. Personally - if I had to choose only one of them I would take FX because I think it has a better list of series like American Horror Story, What We Do In The Shadows and Breeders.
