unfortunately no, while a good person she is also selfish and puts her entire Kingdom at risk due to her own desires, to the point she allows Ursula to gain the power to usurp King Triton and almost conquer the world oceans.. Ariel never means to do this but think on it.. her desire to be part of the "forbidden" human world inevitably puts everyone she loved in danger.

also while she is the titular princess I think it's unfair that people seem to forget that it was Prince Eri who ultimately defeated Ursula - I mean the princes may be given second-place these days but they are still important for what they are.

Ariel may be a nice and innocent girl but she had a lot to learn and so at least in the original film she doesn't quite qualify.
