API and Saffire Pro24 mic pre comparison

Both sound pretty great because the placement, playing, and amp are good. I can hear a difference but if I didnt know which one was which I would not have been able to say. It seems like the choice of mic pre on distorted guitar is pretty negligible once its in the context of a mix. Good mic pres seem more apparent with acoustic guitars, overheads, vocals, and snare from what I've heard. I will say that the difference between the pres and maybe conversion from when I went from my presonus firepod to the focusrite ls56 seemed really night and day to me.
 
Not much in it, the API is a little more forward and has less going on in the lower midrange, gives it a bit more clarity so is a bit more "mix ready" but honestly it doesn't sound like anything you couldn't replicate with some eq.
