The music and art when the music is playing. Both shows have art that show the setting that the musicians/conductor create through their performance. I would say Shigatsu~ is a bit more psychological/drama and a bit less rom-com, although it certainly has rom-com in it. If you were to combine Clannad and Nodame Cantabile, I think you'd have a pretty close approximation to Shigatsu~.

It will wreck you emotionally after making you laugh for most of the series. The cast of characters in both series are not groundbreaking, but how they interact to shape the story (and make you laugh) is what make each anime shine. If you were to combine Clannad and Nodame Cantabile, I think you'd have a pretty close approximation to Shigatsu~.

They both have male protagonist characters who show an exceptional ability to kill people. Grisaia's protagonist is more inhuman from a cruel, abusive, abnormal past. Both shows show the protagonists training how to kill people in both guns and knives. They both have their protagonists put into morally ambiguous circumstances, with a stronger case being able to be made that they are, the bad guys (for at least part of the series).
