Both are centred around classical music/piano. Both have characters competing in competitions and focus on the psychological aspect of that.

2.43: Seiin Koukou Danshi Volley-bu

Honestly, 2.43 is just Haikyuu, but make it more serious and have an edgier main character and boom, that is the foundational premise for 2.43. If you enjoyed Haikyuu as I did, I would 100% give this show a shot.

Both have similar versions of humor and character development. Even though these anime are vastly different you will find many of the same themes and quirks that are similar.

Both are set around the premise of rain and the bonds and romances created from it, while they may be very different through the story, the overall theme of both is centred around the same ideology. Both animations and art styles are gorgeous as well. I believe both are a must watch.
