Baby Steps 2nd Season

Both delve deep into their respected sport's technicality, to a point you have to be seriously knowledgeable about the sport to understand a thing. Both share a similar final opponent, from their looks to their observant patient mind. 

Same sports thematics - this time it's tennis.  

Both are top notch tennis anime. Price of tennis is more drawn out and places a focus on many players whereas Baby Steps is more concise and focuses solely on the protagonist. Baby steps have regular humans playing tennis unlike in prince of tennis where the players are all gods who can jump 20 feet high, a la kuroko no basket. This may be a determining factor for many. On the whole both are must watch sports anime. 

the personality of mc in this two anime is similar. They have strategic skill and make effort from zero without some instant power-ups. 

Both shonens with romance. Although, in one case, the main theme is sports and in the other - music, feeling when watching both titles the same. If you liked one, definitely check the other out.
