S or C?
Much too simplistic an answer...I’m with @LenHazell53 on this one.
Some of both. They are not mutually exclusive.
I favor state capitalism.
To simplistic, all kinds of ideologies fall under the banner of capitalism and even more under socialism. For example National Socialism is more akin to Ultra Capitalism than it is to to Soviet Socialism which is in itself more akin to National Socialism than it is to British socialism. European trickle down capitalism as expressed by Gramsci is basically consensual oppression in exchange hegemonic socialism.
All this before you even get in to other forms of government which despite what Politicians would like us to think is not a 2 horse race between Socialist and Capitalist ideologies.
Personally, representative democratic socialism works for me
Democratic socialism is my choice too. Scandinavian models.
