I think Thriller is the slightly better album but both of them are all time classics that will never get old to the listener. I heard Thriller as a child and every song was a hit. I didn't hear Off the Wall till much later and didn't even realize some of the songs I had heard on the radio over the years was on this album. Thriller gets the praise because of Quincy Jones and Mike having a vision and it coming to light, but Off the Wall should be praised just as much. Both got all time classics on them Thriller just has more. And along with Bad Mike could put up those three albums with any other artist's or group's best three albums and contend.
