With unscalable networks its a mute point anyway, because you cant store all of the transactions on-ledger, which is why I agree with r0ach and smooths arguments that scalability is more important in the long term end goal.
My argument was I don't know which is more important. As TPTB points out the subsets have different properties and tradeoffs and may serve different markets. Or the answer may be none at all is "more important", if it turns out to be necessary to have all of them
