Personally I like the akai eie pro. I used to be a Yamaha guy, had the audio gram 6. It was pretty awesome itself but as far as sound goes I love my akai. It just has more options than my old one. Or any I've owned. Ive had extensive use of Yamaha audiogram (both), m audio interfaces (not going to elaborate, waste of my time and money I've owned 3 different models), onyx satellite (overly complicated for no reason) and what I have now. It's got USB outs on the back for extra equipment, phantom, easy to use knobs that don't over complicate it and it's under $400 easily. Plug and play depending on what computer I'm on. Most times it works but when someone's CPU won't install I just grab the dinner from the website. It's super portable but built like a tank. Dropped it once. Still perfect. Not even a dent. However it's heavy and not lean enough to sit comfortably in a shelf studio or professional studio. It's an awkward box shape lol.
