as a purely practical matter, there are anarchists who would argue over this question (some would rather live and fight in the u.s., others prefer the more socialist option of France, etc.) but mostly anarchists reject the practical option(s) and refuse both examples, since we are, after all, by definition against governments of any kind.
also, i (for one) disagree with the democracy vs authoritarianism and communism vs capitalism continuums. democracy (certainly as it is in the u.s.) is quite authoritarian. and i am not a communist, so i'm not one of the people who associates communism with good things. both communism and capitalism are negatives to me, although i am friends with people who disagree with me about communism, and not so much with people who disagree with me about capitalism (i think there's more confusion and disagreement about what communism means than there is about capitailsm is).
