I've always liked PBS, they have some good quality programming like NOVA, Frontline & NOW. Not to mention the amount of children programming that I'm sure all of us grew up on. Mostly though they don't skimp on quality, I mean most commerical channels that are similar are often filled with bias and for the most part have skewed their programming to entertain. Not that PBS is perfect, but its value is apparent in a world of 200 hundred channels of nothing.
