Cisco 7600 vs ASR 9000

This question would likely be better answered on cisco-nsp.

But the asr9k provides a better roadmap than the 7600/6500 platform.  
These are now quite old platforms in the overall lifecycle. The 9k  
also runs xr which is either an asset or liability depending on your  

Me? I always want a box that provides good diagnostics and protected  
memory over one that does not. Bugs happen, software is imperfect. I  
want a device that provides the best possible debuging information  
when it comes to support time.

These items are not there in regular ios, and IMHO ios-xe does not  
really qualify (but is better, just like the ion/modular 6500 code).
