Prince of Tennis is a manga that accomplish what the mangaka wants, this is your typical battle shonen, not sports but action, everyone has super powers and not figuratively(at some point one guy gets blown out of the stadium), they broke arms, all kinds of bones, people go blind and loose senses all the time. They even turn super sayajin. But has i said if this is the kind of thing you like go for it, i prefer other kind of sports manga (Eyeshield 21, Hajime no Ippo or Slam Dunk). The main characters get good development arcs while the same can´t be said about most of their rivals with the exception of Hyotei Gakuen and their captain(by far the most popular character in the manga, by the final popularity poll). The story is very straighforward, nothing that will knock your socks off. The manga most similar to this one is Captain Tsubasa, two manga with the same strenghts and weakness´s.
