 If you liked Black Cat |  ...then you might like Bungou Stray Dogs |
I labelled the animes as similar as well. I've gotta say, when I originally read the manga it gave me the same feel as Black Cat did. There are some character relationships that are the same, such as Atsushi and Kyouka being similar to Train and Eve. There are story elements that have the same feeling to them, though not in a bad "this one copied the other" way. Both of these series are very good in my opinion (many say Black Cat's manga is much better than the anime) and are particularly worth picking up.

Black Cat and Bungou Stray Dogs don't have the most similar story. In fact, the storylines are very different. But the tone, atmosphere and some of the characters are pretty similar. Both manga have a mix of serious and funny moments (Black Cat has a bit more comedy compared to Bungou Stray Dogs, but this is probably due to the former being a shounen and the latter being a seinen), and the dynamic between Train and Sven is very similar to the dynamic between Dazai and Kunikida, except Train is a lot less suicidal. While both are different, there are still some similarities between the
