Note that the ASR does not support PPPoA which you may be using in ATM.
AFAIK it is not coming any time soon. 
We use G2 and G1s and G2s out perform g1s for forwarding packets.
Cisco upgrade path for us would be to 10k series, of course this changes
the  budget.
Not that an asr plus a 8500 would differ much....
