Those comparison pages come with an explicit wake-up call:
"These are not the only compilers and interpreters. These are not the only programs that could be written. These are not the only tasks that could be solved. These are just 10 tiny examples."
The best benchmark is always your application. All benchmarks are flawed, use your judgement and determine how flawed a benchmark is; Any flaws are relative to your application similarity to what the benchmark tests. An imperfect tool is not a useless tool, so long as you are smart about how you use it.
