I don'r remember a significant difference in performance between the two. But as 18greens said, one could have been very tired (but not to the point of achieving only half the climb rate of a 152) and/or have had a different propeller. It could also have been a particularly heavy aircraft. Or it was a very hot day when he flew it. Probably a combination of factors.
There may have been many factors but I was very surprised at how slowly it climbed and others have made similar comments. Ironically the C150 was the first aircraft I ever flew. I don't recall being ahead of it very much in those days.
Anyway as I said it was delightful to fly I'm sure anyone with 152 experience won't have any trouble with it. (One quirk is the flap indicator is on the A pillar)
