Digital is pretty good because of the ultra low noise, and extra features, i.e. multi effects, and so on. But take this into consideration.... Mackie mixers rule the analogue mixing world. The mixers are built like tanks, and the sound processing is comparable to digital. I chose the DFX12 because it serves just the right purpose for me. If I ever feel the need to get a biger digital mixer, I will save up the flow, and purchase that as well. Something I have found, is with an ever so expanding studio, you can never have too much mixer. If you dont like one choice, save up and get the other.
Choose carefully though if you go analogue. There are alot of Rip off brands out there.
