How does NEM compare to Ethereum?

At this point it's apples and oranges i think.
It would be nice if someone could do a comparison in simple terms for the average joe.
Both claim to be 'platforms' that can build anything ontop of their blockchains, other than that, I don't know the dirty details.
These cover only the basics. As someone else mentioned, our delegated harvesting feature and multi-tier architecture is missing.
