Is new Time Capsule a better router than old Airport Extreme?

[spurbs]

I have an Airport Extreme, I'm guessing the 2009 model? I need a new backup drive for Time Machine and I was thinking about buying a Time Capsule. Will I get better wireless performance using the new Time Capsule?

It's not bad now, but maybe I just don't know any better thanks
