Honestly? I think you need to look at what you actually need out of a box.
At the end of the day, its a 1U switch. If you want to terminate a GRT a
the edge of your network and do some basic path selection then it sounds
like it would be an amazing and cheap fit. On the other hand, I don't think
we can start throwing away core routers yet ;)
Cost wise, Arista seems to be much, much less per port. For example, the

I'm consistently amazed at the density they are achieving for the $$ and I
think it all comes down to what the actual application is here. Most basic
BGP networks do not need all the bells and whistles of the MX104 and will
really benefit from the extra port density. That being said, I wouldn't be
replacing core PoPs in large ISPs with 1U switches!

I've used Arista for a while now (Moving from Cisco / Extreme) and I truly
believe that their software is excellent. They just seem to be doing it
'the right way', If you've not watched it, this video is worth a bit of
your time! https://www.youtube.com/watch?v=VdJZq4dRjf4
Thats my $0.02 anyway
