Hardware is really nice.
Backplane, buffers, just basically “pumping” bandwidth. It’s really good.

However, mlag can show some bugs when having only 1 interface in an MLAG (only 1 side) they had issues with the ifindex numbering in software.
There were OSPF configuration options missing, etc.

In short, hardware is really nice, software needs more maturing. 
Nice for distribution but not for core.
