I watch the same selection including FOX.  I find FOX to be more talk show than news most of the time. All these networks have a few programs that are similar. However I find FOX seems to have a couple of host who have the same guest on most of the time.  Those guest are hardly a guest when they make paid appearances several times a week.  
I agree you have to look at more than one source. More important is you have to be willing to challenge what you are being feed by actually checking things on your own.
