Arista vs Juniper 2018

Hello, we are a colo/cloud/hosting provider looking to replace some older Juniper kit. We have some MX240s(MPC2), QFX5100, EX4300 and EX4200.

I know some items are not EOL, but we want to redesign to a full Layer 3 Fabric with EVPN/VXVLAN.

We have four transit providers @ 10g each. Would need full tables at the edge with the basics..BGP, OSPF, line-rate filtering, Flowspec (which we know is coming Q3 for Arista)

We are hearing lots of good things with Arista in DC and now at edge and wondered what people with experience with both think. If we stayed juniper we would likely do MX204 for edge, QFX10002 core, EX4650 for TOR.

We are also not against looking at edge-core/cumulus for everything but edge also.

Thoughts? / Experiences?
