If you're looking for a core application, then either box 
should do just fine. 

Of course, the ASR9000 would make more sense as I think it 
would be cheaper, is far more modern, and is where Cisco 
will be focusing development for the next phase of platforms 
in this space.

The ASR9000 runs IOS XR, which is quite different from IOS 
fundamentally. Some might argue it's more stable, especially 
if you need a core application.

QoS on the ASR9000 is not bad. I think the 7600 would be 
just as good if you were running the ES line cards.

I'd say take an ASR9000, in case, some day, you need run a 
collapsed core. If you're sure you'll always be running the 
box as a core node, and only if it's dirt cheap, you may 
consider a 7600.
