I've always liked them because Voyager wasn't in a good position to have a lot of recurring characters, let alone children. I thought they brought out human emotion and motherly instincts in Seven, so they served a purpose just by doing that.
I think every Borg person would react differently to having been assimulated in coming out of it.
The twins could very well serve to show that. Borg are usually in a blank state, awaiting instructions. So the twins taking their cues from Seven whereas Mezoti & Icheb were not so "cueless" can show how some can be still in that mindset to await further instructions whereas, Mezoti and Icheb were taking their cues from their surroundings.
Perhaps it is the after effects of once being a Borg that it lingers on introverts moreso than on extroverts.
