when you compare the two economies, try not to compare the overall economy quantitatively. instead, look for stats such as income per capita or inflation rate - stuff which isn't influenced by the size of the labour force, because those stats are generally decieving.
besides the stuff withoutwings mentioned, i think it is also a very good idea to talk about the in/equality of income across the economy, the human development index, inflation etc. do not discuss one particular point for too long, simply because you're only giving a comparison.
