Actually, there have been a couple of outstanding episodes in the last 20 years. I definitely recommend checking out 24 Minutes, Eternal Moonshine of the Simpson Mind, Gone Maggie Gone, Brick Like Me, and Thanksgiving of Horror. However, I feel Trash of the Titans should have been the series finale to the show. They had to move Springfield, the end. After that, Behind the Laughter would have made a phenomenal finale even though Seasons 10 and 11 were stinkers.
