she looks more pretty but i like the character of nabiki more =) nabiki is one of my fav charas in ranma ½

Nabiki is more concerned about money. >:/

I kinda like Nabiki and her hair. Kasumi is pretty, but she makes me think of a mom or the Perfect Japanese house wife. All the Tendo sisters are beautiful. I think Akane is the prettiest, but out of these two there's just something that draws me to Nabiki. Maybe its her short hair. Who knows?

I just think Nabiki is more entertaining.

I think Kasumi-chan is prettier..I'm not sure what to feel about Nabiki-san yet.

In the normal series I say Kasumi, but all the sisters look pretty equal in the OVA when it comes to beauty, just in different ways.

Kasumi is very pretty.

Kasumi is pretty, but so is Nabiki, and Nabiki is just more interesting in my opinion. Kasumi is sweet, but lets say her names suits her considering when things get bad, its almost like her mind creates mist or fog to hide bad things around her, Makes her seem kinda oblivious.

both are equally pretty, but I just think I had more fun reading manga with Nabiki in part of the household mayhem then the ones centered around Kasumi.

Though I do think Kasumi is really sweet.

I like Nabiki from the outside and the inside

In the manga Nabiki looks better.
