Yes precise, you will see where on the spectrum you are working (and how bad it is). And, it's no only saved with the song but you can save scenes with different version of EQs and compare.
Also, you'll start to use only when is really necessary, to fix something, change color only on little details, you'll start to pay more attention on the source. If you have too many EQ fixes you have problems from the source, wrong mics, bad preamp, may be a wrong timbre on the instrument. You know what I mean.
This is very positive. Use of EQ on the mix is not a good sign. EQ on the final mix just if needs minor fixes of space on the spectrum, or may be to avoid some compression on that spot. I learn to think this way.
