Last time I played a Pokemon game was The Red version (so a long time ago).
I dont have much time to play, so I might never be able to beat both game. I know its a personal taste question but to you if you would play only 1 game. Would it be Pokemon White/black or X/Y ?
I've always felt that Pokemon has gotten less fun with each installment. I don't know if that's truly the case or if it has to do with getting older. However, I would probably recommend X/Y over Black/White since it's newer and the community is really active again. Also seems like there's much more "keep-playing" value.
