The relative benefits of adding MAB depends on how much MAB you already have, and nothing else. For adding INT it depends on the spell, how much INT you have, and how much INT your target has and nothing else. The more MAB you have lessens the benefit from adding more. The more INT you have, the lower the INT your target has, the lower tier the spell you are using and the higher level a spell is within the tier you are using, all lessen the benefit from from adding more INT.
