So even though the large thought units with more faces has a higher raw information transformation power, it will be slower at simple task than the smaller thought unit and will still consume more energy than the small thought unit. This makes large thought units less efficient at executing simple tasks.
The area where the larger thought unit will be able to shine is in a complicated task, such as predicting the weather. There are too many factors to consider for this task, so the small thought unit will have to take many cycles to complete the same thing that the larger thought unit would be able to complete in one cycle.
At the end of the day, thinking in the thought unit and coming to the right outcome is a matter of chance. More complex thought units have more chances to make mistakes, while simpler thought units don't have as much room for error. But the two of them have their advantages and areas where they are better suited.
