Anyways in overall if you liked shigatsu wa kimo no uso, then you would probably like it. Also goes for whoever that likes music anime/manga. The plots somewhat different and similar at the same time.
For example both protagonists start out as a character who quitted whatever they were playing(arima- piano, aono- violin)
Also I think ao no orchestra has more interactions with more characters, so you can also see experiences of other characters not just the main protagonist
It’s a pretty good manga. I would recommend it. The art is really good too. Depending on the situation, the art is either rough or clean. It’s interesting to read
