Tokyo vs Kyoto... I dunno, maybe it's like Madrid vs Barcelona. Barcelona is more outwardly beautiful and aesthetically pleasant and easy to fall in love with at first sight. But Madrid really grows on you after a while, and it's now my go-to place for vacation in Spain.
I can't really make a similar statement in comparing Tokyo vs Kyoto, because my perspective is that of someone who lived in Japan and goes there all the time. But personally, Kyoto is a place that instantly impresses you as being quaint with a distinct atmosphere, and yet I don't really ever feel like I need to spend more than a couple days there again. Tokyo just offers an endless array of a lot more things to see, do and eat. But again my perspective is probably a lot different than a tourist visiting Japan.
