Well, that makes it easier lol:
Who has a better flow? Yuna
Who is more comfortable on the ice? If Caro is out of the equation, I don't know. Adelina seemed comfortable in front of the crowd, but is that the same as being "comfortable on the ice"? Yuna looks much more at home on the ice than Adelina (skating style is choppier = lacks grace - but there's already another question about gracefuleness, so I'm still at a loss of how to answer this one).
Who is more sure-footed during the performance? Yuna
Who skates with two feet more? Again, not totally sure, but Adelina's choreo stands out in this respect
Who skates faster? Yuna
Who skates to music? Yuna
Who skates with more ice coverage? Yuna
Who skates more effortlessly? Yuna
Who skates more gracefully? (carriage, style, lines, etc.) Yuna
Whose skate has more intricate linking elements? Adelina
Whose skate has more personality and/or originality? I'm split on this one. Originality (although not my taste) = Adelina, Personality (albeit understated) = Yuna
Whose skate excites the audience more? Adelina
