Sure, but I'm saying something more specific than just "head-and-shoulders the best". I'm saying we should entirely ignore overhead and in fact pretty much ignore what the charity itself does at all (how much of your donation goes to fundraising? How much goes to lavish hotels?), and just look at the actual malaria rate in the children they treat.

I highly recommend reading the New Republic article I linked to, it talks about all this in a lot more detail.
