There's no need to mention what they believe or if there's actually a need to acknowledge that Bitcoin is superior because it IS superior by all comparisons. People will know it, either the easy way or the hard way.

But they will always claim that their network has higher transaction throughput and therefore "scales", but how do we define "scale". Higher throughput but sacrifices decentralization? That's not scaling. It actually scales the network down, reducing node count, and therefore centralizing the network.
