I like the PreSonus stuff. But then again, Focusrite is nothing to stick your nose up at. Both build qualities are good. Both sets of preamps are good. So your only real criteria would be, which one is laid out the best for your purposes? Which ones have the features you like most? I have purchased equipment in the past with those 2 criteria only. You already know about the quality level regarding both units. They're about equal. And that's what makes a decision so difficult. I might also add, you have freaking cheap low-end Pro microphones, so why worry? What are the price differential differences? Does it leave you enough money to purchase a quality sounding SM 58? I mean your computer monitor is more expensive than your entire recording chain? What's with that?
I sometimes don't understand people's equipment selection criteria?
