MPLS VPN, TE and QoS, If all you need in one BOX than better you go for
Juniper M Series. Juniper M10i or M120/320.

You should find out very carefully if or not you can live with LAN
card limitations. Without knowing specific of your QoS requirements,
it's very likely that you are terminating customers to subinterfaces,
effectively requiring HQoS which LAN cards do not do.
 Other limitations that pop in my mind are, no vlan local significance,
no IPv6/uRPF (and chassis wide strict or loose in IPv4), no IPv6 CoPP,
no TOS byte transparency, either you lose up-to /128 lookup or L4 lookups
in IPv6.

If you find out that you can't live with LAN cards, the main attraction
of 7600/6500 goes away and you have much more options to choose from.
ASR1k, MX, M, GSR, CRS.
 But if you are aware of all the catches with LAN interfaces and can
live/workaround them, it's very good value to your money. However, in my
book they suite much better LSR/P role than LER/PE role.
