I'm guessing that "ATTACK OF THE SHOW," & "X-PLAY" may have different Writers & Producers.
AOTS covers a bit of everything in the field of Entertainment (Movies, Video Games, Comic Books, Toys, Internet Sites, E.t.c). XP on the other hand, deals primarily with just Video Game-Related PreViews & ReViews.
Both shows have the Hosts read out Witty, Cynical & Sarcastic Commentary (primarily for the sake of being Funny). Often times though, it will boil down to whether the people watching AOTS or XP, like or dislike the various Personalities who host the Shows. Sometimes, when some fans do not like certain Show Hosts, they tend to not like what they have to say, or how they say it.
Ultimately, I go based on what Topics AOTS covers in a particular episode. Thus, I tend find some of their Episodes more interesting than their other ones.
As for XP, I almost never base any of my Video Game Buying/Playing Decisions, on the outcome of their highly "Colorful" Reviews. The show has changed so much, that I primarily view it for Gaming Entertainment, more than I view it for any Serious Gaming Information.
