In both manga the male protagonist has to take care of a rather cute animal girl who has tendencies to act animal like. Fans of one of those manga could possibly like the other one, but for me Come Come Vanilla! is the better one among those two.
Vanilla from Come Come Vanilla! and Yusuzu from Inakami seem to be similar characters in both appearance and personality. Oddly enough, male leads in both series seem to be likable and they actually don't get beaten up by the girls around them (at least not yet). Because of all that (and some other reasons as well) those two series feel alike, so odds are if you liked one, you'll like the other one too.
If you liked the relationship between the main duo from one of those two manga (Darumiru and Ariyuki in Suashi no Meteorite and Vanilla and Rikuo in Come Come Vanilla!) than you could try reading the other one too. Basically in both of those sries a guy has to take care of this somewhat adorable girl.
