diffrence between two bgp router router:

Hi

I try to compare two routers to new DC: Juniper mx240/480 with card "R" and Foundry NetIron XMR 8/16000. There is big diffrence in price. I don't know Foundry router's so it's hard to me to compare this two routers. Someone has expierence with both ?

configuration Foundry:
NI-XMR-16-AC
NI-XMR-10Gx4
NI-XMR-1Gx20-SFP

and Juniper:
MX240BASE-AC-HIGH
DPCE-R-4XGE-XFP
DPCE-R-40GE-SFP

thx for help
