By far!

I love both, but Nani and Lilo's is more realistic in terms of problems :)

Always!

They feel like actual sisters who have actual problems and concerns yet still love each other no matter how many times they fight. Elsa and Anna's issues just seem too contrived, underdeveloped and forced. Both sets have to deal with the sudden loss of parents and the older sister has to take on a leadership/parental role while the younger sister tries to compensate the lack of attention by having strange hobbies. The differences between these two groups however, is in the execution. We see Lilo try and make friends but they reject her because she's too "weird" so she goes back to making voodoo dolls. Anna talks to paintings and to her sister through a door but we never see her interact with anyone else. Seriously, there wasn't a nanny or a maid for her to talk to? Nani we see struggling to maintain a job, a house, and raise her little sister all with social services breathing down her neck. Elsa is supposedly being groomed to be a queen (by whom or how we never see) but locks herself in a room out of fear of her ice powers. The problem though is that this only raises questions on what she does day to day, how she eats, how she learns to govern, etc. With all of the training Elsa needs it can be presumed that there are a lot of people at the castle, which makes me wonder how these two can be isolated with all of this presumed activity around them. The main problem with Frozen is that everything is told instead of shown so we have to assume a lot about these two characters instead of letting the story show us how they grow and develop.

I got so much more of the "relationship vibe" out of these two.

they talk, they fight, they make up, the act and feel like real sisters

They are soo cute!
