They both have a similar vibe, showing the story which includes present and the past interleaved with a bit of sadness about things already gone. However Omoide Poroporo is a little bit more down to earth and realistic while Omoide no Marnie has more on dramatic and romantic sides. Also they share the first word in their name which means "memories"
