The Democratic Socialists of America, or the anarcho-communists?
Personally, I'm leaning toward the Democratic Socialists of America. From their website:
Democratic Socialists have long rejected the belief that the whole economy should be centrally planned. While we believe that democratic planning can shape major social investments like mass transit, housing, and energy, market mechanisms are needed to determine the demand for many consumer goods.
So they're willing to allow some degree of free enterprise, unlike the anarcho-communists. And while they advocate harsh control over everything else, their overall program isn't much more statist than so-called "libertarian socialism" would be in practice.
Sadly, the Democratic Socialists of America may be preferable to the anarcho-communists.
