I remember a few years ago on the list for RangeVoting, we did an 

analysis of Voronoi versus SplitLine.  We found that Voronoi is too
compact:

Assuming that we are stupid enough to use plurality, thus subject to 

DuVerger's Law, Voronoi tends to generate districts with a
60%/40%-party-balance.  That means that electability means nothing, so
one ends up with extreme partisanship.  SplitLine generates districts
with a balance of 45%/55% so that electability is importants, so that
politicians are willing to actually govern instead of obstruct at best,
or try to create communist states if they are on the left or fascist
states if they are on the right at worst.

¡Peace!
