They definitely were, once upon a time. 60 Minutes has lost its edge over time; I'd say they never really recovered from the episode with Brown and Williamson (dramatized in the movie "The Insider"). I don't know when 20/20 disintegrated, but when I see it now, I can barely distinguish it from Dateline NBC, which is little more than a new cartoon for children.
Like any show, 60 minutes has its ups and downs, bad stories and good. But on the whole I still watch it and find it very high quality and well produced.
Other news(y) shows I like (some of the time): Q&A (on C-SPAN), Charlie Rose, Sunday Morning, and Meet the Press.
