[nsp] sup720-3bxl experiences?

[Saku Ytti]

 Anyone have anything good/bad to say about Sup720-3BXL that I can't
read from CCO? I have hard time figuring out why would anyone without 
existing hardware shop GSR as their new Ethernet platform when Sup720-3BXL has
multiple times cheaper port pricing.
 Only difference that I found out is lack of hierarchial QoS, which might or
might not be an issue. (for P shouldn't matter, but for PE it might)

 Is the real life experience with Sup720-3BXL in par with CCO
promises, look very (too?) cheap to be true. Where's the catch?
