YUI, hands down. The song has so much emotion in it I feel it doesn't even compare to the two others. My own opinion, of course.

Sidenote, I always thought Ayu should do a cover of TOKYO by YUI... I feel she could relate to it a lot. Both came to Tokyo from Fukuoka at an early age to find themselves. Also, both grew up without a father, not that that has anything to do with the song exactly, but it's still a thing to know... Ayu singing TOKYO, with a guitar by her side. Priceless.
