Toughie! I really can't pick. I remember when NSync came out, and I thought they were like the younger brothers to the already established Backstreet Boys. Ultimately it seems NSync surpassed them, but I have a soft spot for old-school BSB. I think they were more melodious and heartfelt. Still, NSync was stronger in the vocal and dancing department.

Don't know.

But at the end of the day... Justin Timberlake is an annoying baby and Nick Carter is a baby and doing reality TV.
