The recent (august 2015) news is that nem admins/developers have gone extremely desperate in nem thread, and they have now started deleting even factual posts if it's critical of nem. Here is example of deleted post
Then, can we say NEM is
3.33 times(370/111) efficient than Etherium, at least until now?

Look at the daily volume. That tells you the real difference between both, and nem is not even close. 2 BTC daily volume vs 5000.
