i really don't have a preference at all. ٩(๑❛ᴗ❛๑)۶
publishers are very rarely ever looked at for me to decide if a game is worth trying. there's too many indie games and studios that have created beloved games that a publisher doesn't carry as much weight as it used to, in my opinion.
i used to adore voltage as it was one of the only english otome publishers i could get my hands on, but it has such a wide array of games that it's hard to ignore the issues of one series of games and repetitiveness versus their newer releases trying out "moderately" new formulas.
i'm sorry, it doesn't really answer your question but i think the saturation of independent publishers and issues of others makes it hard to determine one as a be all. (๑•̀ㅂ•́)و✧
