As dot alluded, my personal preference is specific to my conditions, and are pretty well detailed in my answer to the question Lawrence linked to in his comment. I do, however think there are ways of exploring what makes them different that can help someone figure out under which system they might prefer to operate.
I think what is important about thinking about living in a democratic versus a totalitarian (which I think might be a more accurate word for what you called authoritarian? I could be wrong) state is that the tactics and forms of organizing (little "o" organizing) will vary based on the nature of the regime. The potential repercussions of conflict with the state are often far less severe in a democratic state (I am presuming some things abut the nature of the legal system in said state) than in a totalitarian one. I don't place a value judgment on this, it is an observation. In a democracy people often get more time using contestation as a sort of play where we can sharpen our skills and experiment over time with different tactics. In a totalitarian regime, it is more likely that groups will organize quietly and under the radar, biding their time until attack is feasible. One of these risks becoming rote ritual, one threatens to possibly never materialize. Neither is better, or necessarily preferable, just different
Similarly, a capitalist society provides certain advantages to an anarchist over a communist one, but the converse is also true. As an example: in a communist economy, the grim realities of centrally managed distribution of both production and products lays bare the inefficiencies of state control while in a capitalist one, people are easily distracted/appeased with new shiny things, or pacified with the perception of being middle class and upwardly mobile. On the other hand, a capitalist economy often creates such stark contrast between the very rich and their access to power (versus all the rest of us), while in a communist state, this might be somewhat more obscured (although obviously party officials almost always end up being an oligarchy).
