I don't necessarily agree with your conclusion, but I will admit you can't put KSUID and Snowflake in a room and declare either of them the winner.

I would argue that doubling your key-space in the case of KSUIDs may have just as much of an impact as coordinating node ids in the case of snowflake (and in fact the snowflake technique only runs into coordination problems when you're at pretty extreme scale).
