Ping Pong the Animation, Shakunetsu no Takkyuu Musume Recommendations
While both are typically different at their core, they manage to take their portrayal of Ping Pong more seriously than other sports anime. Fast paced, full of sweat, tests of agility and the like without completely decaying off of realism. It's a moe series, yes, but its showcase ping pong is about as good, if not as good, as PPTA's.
A great deal of ping is pong'd. They both have memorable soundtracks as well.
Both shows are about Ping Pong, and they both have kind of unique or different art styles, and it's good.
