Good questions! I'm assuming you're talking about Analog consoles. I don't think analog consoles are "better" for mixing, but for recording, I don't think it gets better than having a nice high end 24 (or more) channel console. Without getting into the qualities of a high end board (mic pres, dynamics sections), this is where consoles are king - for using them to record your tracks and have the console be the "brain" of your recording and routing set up.

For mixing, I prefer staying "in the box" because of the sonic neutrality, not to mention how insanely expensive it would be to have analog versions of all the processes I currently use for mixing and how easy it is to route tracks to effects in a DAW.

In a mixing situation, the console's master section is essential (having output control, the ability to mute and phase flip, route the master output to several sets of monitors, even have a talkback and dim section). I've taken care of this by using a Crane Song Avocet, which is a mastering-grade DAC and monitor controller, which has an outstanding control panel that does a lot of the same things that a high end console's master section does for output control, except it has a mastering-grade stepped attenuator (not usually found on consoles).

This said, one of the best things about using a console is the tactile control you have over tracks with faders, knobs and buttons. For this, I use digital consoles which allow me concentrate more on the music without having to stare at the screen and would definitely not like to be without them (my control surfaces use the same brand of faders and even the same function protocol as an SSL 4000). If I had the need for an analog console (I don't record) I would definitely want one as the brain of my setup. Thanks & good luck!
