Best Boy Band Of All Time???

We had an argument today at the office and we narrowed it down to 2 bands BSB and 'NSYNC. Now I may be a little biased but The Backstreet Boys are THE Best Boy Band of my generation! And here's why..

Backstreet Boys:

• Best Selling Boy Band Ever with 130 Million records
• Millennium sold 30 million albums worldwide

'NSYNC

• Justin Timberlake

Don't get me wrong I love 'NSYNC but they're no BSB! Who do you think is the Greatest Boy Band of All Time?
