6500 is LAN/DC services switch, there's no need for HQoS in that
scenario usually. MX80 is a router and doesn't offer HQoS, which is
a worse problem. With Sup2T in 6500 you can pack a pretty good QoS
capabilities, it lifts the uRPF restrictions of previous generations,
and adds Flexible NetFlow along with good scalability for ACLs and
NetFlow cache to the portfolio of tools you can use. It also offers
truly "routed" approach to dealing with VLANs, as you have BDs and
LFIs to flexibly map/remap VLANs, and terminate L3 where do you want.

For scenarios where ASR1k doesn't scale for price/performance reasons,
use ASR9001.
