I mean, the other houses are nice and all, but Hufflepuff feels like a home.

It's not the traits. I think that maybe Hufflepuff encourages hard work and cooperation. It's the attitude. "Everyone belongs here. We're family." You don't see that in Gryffindor so much. chrystanza said that Luna was an outcast in Ravenclaw - if it weren't for Harry and Ron, Hermione would have been one in Gryffindor. We know almost nothing about Slytherin in that sense, so I can't say about them.
