It's going to depend heavily on what EQ plugins you use, and how much you care about the color of vintage analog EQs in your mix. There's lots of ways to add color to tracks, or to the master bus, etc. A clean digital parametric EQ, or especially a linear phase EQ, will give you the cleanest sound, but sometimes "clean" isn't the tool for the job. There are lots of Pultec clone plugins out there, and I honestly have no clue how accurate any of them are, because I personally have never used the original hardware.
