In my personal case I think when the default value is "show sector labels", it is annoying BUT I also think it should be like that cause when it's not by default, I'm pretty sure looooots of players don't know about this option : new players, old players who come back after x years, current active players who don't read the forum and don't talk to other players (and these ones are the big majority of current players into the game).
So I voted "I want a choice", cause I think the sector labels should appear by default, and we should be able to choose if we want this default value to stay like that or not (like in an option in the settings for example).
Like that everyone would know about it (cause the labels would appear by default) but everyone annoyed with it could change the default value as they want.
