In its current form your question leaves me perplexed.
1 is not a network, and although hypothetical, for the purpose of seo 2 isn't either.
The number of links is so piddly small that I could do it in an afternoon, so I'm assuming you are asking, should you spend your seo budget on two sites rather than one? Meaning each site will only get half the juice.
In which case 2 (but actually times it by ten to begin with)
