We (Netflix) have been deploying the previous gen (7500E) as edge routers
for about two years in high traffic, low route count applications in our
CDN, and have been working with Arista for almost as long to improve route
scale so that we could turn off all our traditional routers.

The features that enable full routes on Jericho are running in our
production network today and we also have the 7500R and 7280R working with
full tables.

I can't speak to MPLS, but for our use case (all L3, very high-density
10/40/100G, BGP, IS-IS and light QoS), it's working well.

So, yes, I'd say those two products are quite viable and competitive
options in the edge router space.
