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
network.
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).
