Shigatsu wa Kimi no Uso, Koe no Katachi Recommendations
This recommendation isn't to say that you'll enjoy Shigatsu wa Kimi no Uso if you liked Koe no Katachi, but if you liked Shigatsu wa Kimi no Uso, it's very likely you'll like Koe no Katachi.
Describing why this is the case is difficult. Too difficult
In both this cases I recommend the sub, although the english dubs of both are also very well made. The issue is that the translations are too literal for Shigatsu wa Kimi no Uso and too loose for Koe no Katachi.
If you want to get very emotional, this is also a good request.
both heartbreaking anime about a boy and a girl bonding together. eventually, something happens, which make both anime amazing. these anime will affect you and potentially make you cry
2 Very emotional series wich i really liked watching both talk about how important friendship can be for all of us :)
