I don't think that any sort of on-chain scaling could be on par with LN. The different mechanisms behind LN can support orders of magnitudes more transactions for a much lower price. And you can have many independent LN like networks. Some of them might provide functionality not contained in Dash Evolution. That is why I think Dash should not be afraid to support LN.If I understand the technology correctly (someone correct me if I'm wrong), Dash Evolution and masternode network will provide a functionality that is on par with Segwit and Lightning Network.
