HD Tach (Pro) is the more common one to use. Atto, albeit somewhat dated, is another one.
The more important question is, what is the comparison base? Does your number XXX result mean slightly less or more than result YYY, or is it a huge difference? How do you interpret results? How can you compare to others and should that be a worry?
Have you done the PPBM5 Benchmark ,another test often used.
