It's one of those cases where there is no perfect system, only tradeoffs among imperfect proposals.

Here, for example, you mention influence of a larger part of the voting body, but that runs counter to my preference of accountability to the smaller community over, perhaps, a national coalition.

But such goals and success metrics of any representative system are pretty subjective in the end, depending on how a person's values balance those tradeoffs of the imperfect options available.
