They may be more efficient but when you need to run a dozen different containers simultaneously and you want each one to use a modest amount of memory, 16GB falls short. The issue is not efficient vs. non-efficient. It is scale. If I was writing a single web app on two containers sure 16GB would be fine. I am not though, and the scope of what I work on requires more memory.
