While most people assume that the best charities are only slightly more effective than average, experts estimate that the best charities are often 100 times more effective.
On the Giving What We Can charity comparisons page, there is a list of concrete examples of how effectiveness varies between charities. For instance, providing deworming treatment is roughly 100 times more effective than merit scholarships are for improving education.

The difference in effectiveness can be even bigger when comparing charities working in a wide variety of causes.

These huge differences in effectiveness provide us with an opportunity to do much more good with our charitable dollars if we choose charities strategically, rather than simply choosing the charities that we are familiar with, or the ones that are most convenient.

One of GiveWell's top charities for the past several years, AMF provides anti-malarial bednets to people in need. 

From Givewell: 
What do they do? AMF (againstmalaria.com) provides funding for long-lasting insecticide-treated net (LLIN) distributions (for protection against malaria) in developing countries. (More)

Does it work? There is strong evidence that distributing LLINs reduces child mortality and malaria cases. AMF conducts post-distribution surveys of completed distributions to determine whether LLINs have reached their intended destinations and how long they remain in good condition. AMF's post-distribution surveys have generally found positive results but have some methodological limitations. (More)

What do you get for your dollar? We estimate that the cost to purchase and distribute an AMF-funded net is $4.95, or $4.65 excluding in-kind contributions from governments. The numbers of deaths averted and other benefits of distributing LLINs are a function of a number of difficult-to-estimate factors, which we discuss in detail below. (More)

Is there room for more funding? We believe that AMF is likely to be constrained by funding. We estimate that AMF could use up to an additional $37.8 million to support LLIN distributions that will occur between now and late 2023. 

AMF is recommended because of its:

Focus on a program with excellent evidence of effectiveness and cost-effectiveness.
Processes for ensuring that nets reach their intended recipients and monitoring whether they remain in homes and in good condition over the long-term.
Room for more funding – we believe AMF will be able to use additional funds to deliver additional nets.
Transparency – AMF shares significant information about its work with us and we are able to closely follow and understand its work.
