We use mainly mpls/p2p pw so much for wholesale/business Ethernet, CBH, and various other purposes.  Still using mpls/vpls occasionally… oob mgmt backhaul.  For DC interconnect, I use evpn/mpls, since I have an mpls network.  We are an SP, so mpls has been the basis for our network-based-L2/L3 VPN’s for 10 years or so.
