One can argue that bias is a mistake, so removing bias improves decision-making. So asking whether removing bias is "more important" than improving decision making is a non-sequitar: removing bias is a tool towards that goal. In a sense it's "less important" because other tools might do the job better, and in a sense it's more important because simply desiring to improve decision-making does nothing without tools to implement that desire.
