Ringworld is excellent (and the first couple of sequels), though I don't like his other stuff.
Speaking of overrated, what's the big fuss about Heinlein? Starship Troopers is okay, and I read Have Spacesuit, Will Travel when I was a kid and enjoyed it. But IMO he's not even close to Asimov or Clarke.
Another overrated book is The Forever War. It's alright, but it's nothing special. I dunno. Different blokes different strokes, I guess.
