These types of comparative testing results will vary depending on who is doing the testing, what they are testing for, what versions of the firewall software is being tested, etc. There are no universally predefined set of standards/criteria for testing and each test will yield different results. Thus, you need to look for detailed information about how the tests were conducted, the procedures used, and data results. Then you have to consider the features offered by each firewall, the amount of resources utilized and how it may affect system performance.
Choosing a firewall is a matter of personal preference, your technical ability/experience, features offered, the amount of resources utilized, how it may affect system performance and what will work best for your system. A particular firewall that works well for one person may not work as well for another. You may need to experiment and find the one most suitable for your use.
