Pros
Pro Dromaeo uses tests from several different tools
Dromaeo is different from other JavaScript benchmark tools because it uses it's own tests as well as tests borrowed from SunSpider and V8.
Pro No arbitrary numbers as results, this makes the tests easier to understand
This benchmark tool won’t show you any arbitrary numbers as a result, just the time it took to take each individual test. This is very helpful since it gives you a more detailed view of what is happening behind the scenes and how each browser handles each test.
Pro SunSpider focuses on real world problems
Unlike other benchmarking tools, SunSpider completely avoids using microbenchmarks, which attempt to test the performance of a "small" amount of code at a time. Instead, SunSpider mostly tries to focus on the problems developers face with JavaScript today, such as generating a tagcloud from a JSON input, 3D raytracer, cryptography tests, code decompression and many more.
Cons
Con There's no easy way to compare tests
Unfortunately, Dromaeo does not have an option to save your result in order to compare it to others. The only thing you can do is to bookmark your results and then compare them.
Con As browsers get faster, tests may become too easy
Although considered by many to be the most comprehensive benchmark tool out there, the fact that it avoids using microbenchmark to test the code efficiency means that as browsers start to get faster at running day-to-day tasks, SunSpider's tests may start to become easier, especially compared to tools that use microbenchmarks.
