I agree with that, but DC Cab was the apex for everyone involved. A true underrated classic.
That said, I kinda like Maher's show, if only because he gets some smart guests and I also think he's a pretty good interviewer. He also get's some terrible guests, unfortunately. I also hate when his intelligent conservative guests get shouted down and booed by the crowd, or his stupid uninformed liberal guests get cheered for every inane comment. But overall, I find more interesting stuff on that show than most punditainment.
