Let if I could translate what she said.
#1 Wide Angle 14>20) There aren't too much difference in the quality of the two lenses. She likes the 14mm better because she can capture more in the picture.
#2 Bokeh 20>14) She likes the 20mm more because it can isolate the subject from the background better.
#3 Macro 14>20) She likes the 14mm more because it is sharper. She also likes to edit her photos so that the difference in focal length does not matter to her.
#4 Self-Portrait 14>20) She likes the 14mm more because it is not as close as the 20mm. And her head is too big with the 20mm.
#5 Night shot 14=20) No difference between the two. She also mentioned that the two lenses are not sharp enough at night.
