personally I like both rima and utau.I mean rima is so funny.And utau was made such a strong character who cares for the people she should.But between these two it would be utau.It is really hard but I have way too many reasons to explain.But I did not chose yaya cause well she is funny but not as funny as rima and not as great as utau and amu just gets on my nerveres.so I have to fan utau over all of them.And ain't rikka missing too?I would not chose her but she is missing.
