Both animes are centered around sports. The main character is male. Both become stronger throughout the anime.
Both shows feature distinct schools and characters with unique play styles
Both of the main characters develop into better players throughout the show
I would say more but don't want to accidentally spoil anything. The shows give off a very similar feel as the characters and teams develop and overcome challenges.
