Fundamentally, a project's focus is absolutely important, especially when a comparison is asked. When you ask the question: "How can OVN or ODL solve being a backend layer for Neutron?", for example, the answer with OVN is simple: You do it this way, and it works. For ODL, the question is much more nuanced, as it depends on *what* components in ODL you are using. Also, yes, the comparison between "ML2+python agents" vs. "ML2+OVN" is much more relevant IMHO.
