Internal Vs External Mixdowns

[jasedee]

I hear this statement alot....

"The summing of the internal busses on a DAW are done with numbers, not voltages, so this is your biggest compromise. A better option would be mixing through an analogue console...."

So my question is this: When mixing down, is it better to take my main mix (on my Mackie stereo line channel) and route it back into the computer to record the mixdown, or just do it internally (export/bounce to stereo) in my DAW????

What do you guys reckon (do you even care?)
