I would think you would have to try one in order to be able to say whether they are overrated or not. If you could say you ran without one, then ran with one, then ran without one again, and saw no benefit with the skimmer, then you could say they are overrated. But saying they are overrated without ever trying it, im not sure how you would justify your opinion.
