It depends on your definition of quality.
Do I think Madden is a football sim? No.
Does it have it's "Throw-the-controller-against-the-wall moments"? Of course.
Do I have fun playing it? Sure as hell I do.
It all depends on what mindset you're in. Buying Madden year in and out thinking it's going to be a sim is stupid. We all know what Madden is.
