I think it's the quality of the gimmicks. There's no real stinkers in 2 but there are in 3 like the sewer gas level with reversed controls, the slooow one with low gravity, and I remember the waterfall elephant levels being very slow paced and boring too. Can't really think of bad gimmicks in 2. Maybe the balloons over lava? But they don't overstay their welcome.
