SD-WAN implementation

First off, I hate the term SD-WAN; it implies that running full tunnels is somehow new. All of the high end SD-WAN appliances from VeloCloud, Silver Peak and Cisco load balance at the packet level. I would assume they are all using EIGRP because why invent the wheel but I don't know how much of the spec Cisco published in their informational RFC? Cisco is most certainly using EIGRP. I was hoping to gain some insight from people that have used these high end appliances on how the manufacturers implement load balancing at the packet level? In my experience with MikroTik load balancing at the packet level causes all kinds of issues with out of order packets, etc.
