Given that the more of my code I can see on the screen at once, the more I like it, I tend to try to use a more horizontal style. However, I try to avoid piling up too many assignments (3-4 max), and only when the RHS expressions are simple.

I think there's a reasonable argument for
local a, b, c, d =
      e, f, g, h

This gives you some level of alignment between value and variable that
one-lining it doesn't, while being more compact than a series of
one-variable assignments.
