to consider
'überlegen' and 'dominierend' are not true synonyms in the meanings intended here, but they can be confused because of similar ideas of strength or precedence. 'überlegen' is a verb here and means to think, plan something, or change a decision. 'dominierend' is an adjective and describes something that has the strongest effect or holds a controlling position. When it is about thinking and deciding, use 'überlegen'. When something determines the most in a group, a room, or a situation, 'dominierend' fits.
