SPAN is excellent.
I like analyzers that can show you the analyses over a longer period of time.
PAZ for instance does not have that option. Most accurate? Well that also depends on display, zoom and speed settings.
A good analyzer will give you parameters that work in the same way as clip does. A light or other indicator shows you a certain threshold is being met.
In that sense as long as the UI agrees with you, there's phase and db metering, it's all good.

its to do with the eq's, getting the right ones for the different sounds kick 100hz, snare 200hz etc etc
im sure every pro producer uses them in the studio
Yup, most analyzers have musical grids though. But some engineers and producers might like the 32/48/64 band appraoch or even more musical oriented bands.
