I'm just thinking, that for an Internet edge router you might just need
loads of BW -not that much pps rate, (no need for full line-rate at 64B),
and not that many features (just decent flow telemetry) -unless you are
doing some proactive DDoS filtering on the box -in which case you need a
clever and "pps-powerful"  NPU. 
In CP you need fast and safe BGP implementation with loads of features,
something that have decent BGP error handling and speaking of CP a good CP
protection. 
Regarding the buffers if it'll be doing just 10GE to 10GE..., well during
DDoS all that traffic is mangled anyways (10x10GE->1x10GE)-unless you expect
something important to arrive over the internet -like voice (in which case
again you need features and decent HW implementation). 

So what I'm trying to say is that NCS5k with no data-plane features but
loads of BW and "maybe" a decent CP (-cause it's XR-based), might be the
right choice?
