Just in general.

BGP convergence time is not too bad, but the Intel-based MX is a lot
faster in that regard, from experience.

No real complaints about the ASR9001, to be honest, apart from the
heavy-handed IOS XR upgrades.

Power budget dictated the RE, which is why an Intel-based RE will never
come to the box.

The box was designed to compete with the ASR1000, which offers Ethernet
+ non-Ethernet versatility.

The MX240 and above and the ASR9000 chassis are not suited to
non-Ethernet line cards, even if they support them.
