From "Hangin' Tough" to "Dancing With the Stars," New Kids on the Block have been part of pop culture in three decades. We asked reality-show veteran Jordan Knight to vote for his favorites in a smackdown of 1990s pop forces.

Backstreet Boys vs. 'N Sync

Justin Timberlake and the boys because "they were more like the New Kids. They leaned more urban and they were more fun."

Britney Spears vs. Christina Aguilera

Britney is "sexier, she's funner and she can act really well."

"Fresh Prince of Bel Air" vs. "In Living Color"

Sorry Will Smith, but the Wayans brothers, Fly Girls and crew were a "phenomenal cast."

"Wayne's World" vs. "Dumb and Dumber"

"I'm a big Jim Carrey fan."

"Seinfeld" vs. "Friends"

Jerry and friends win "because it's more goofy or slapstick."

"Beverly Hills 90210" vs. "Party of Five"

His preferred number is "Five" because of its cast.

MC Hammer vs. Vanilla Ice

It's Hammer time: "Vanilla Ice had only one hit, and it's hard to get into someone who has only one hit because you don't know what they're about."

Mark McGwire vs. Sammy Sosa

"Neither. I don't trust either one of them."

Notorious B.I.G. vs. 2 Pac

The Massachusetts native votes East Coast because he likes Biggie's voice better.

Chicago Bulls vs. Dallas Cowboys

"The Bulls for sure, for sure. I was nuts over them. Michael Jordan and Scottie Pippen."
