It "hurts" me to choose, because I deeply love both, but I think this one would have worked better, seeing as it gives the sisters' relationship more depth and showcases more of the fearless Elsa.

Life's too Short does a good job at showcasing the sister's arguing but I don't really like the melody.

By far.

It reminds me of how my sister has been there for me through anxiety, depression, and self-imposed isolation all these years.

EDIT: What Silverrose said though. I think the other could have added more meat, depth, conflict, and actually showcased a realistic sister/sister relationship since, you know, sisters fight and disagree, and our differences chafe at us.

scarletunicorn summed up my thoughts.

Both are great.

I do like Life's Too Short, though.
