I was trying to hold my tongue and not gush over PolarDesigner but I shall no more. Kidding, but I truly find it far more interesting than predefined mic models. I didn't expect that going into it, but despite having the Edge models and Sphere available I only ever use those for previewing, always use AA PD for my actual mixes. The ability to alter polar pattern per frequency band is huge and has a ton of real world advantages. It accomplishes things not possible with traditional approaches (i.e. EQ).
When I started testing it I first tried matching the sound of some Edge modeled mics. Was simple to get there by ear. Then I tried matching other mice I had on hand by ear, same result. Then I realized focusing on matching and modeling missed the point and starting creating idealized responses for the specific song context, and that's where the magic is.
Okay, I'll stop, but I am a fan of that one. The obvious drawback with any dual channel solutions are the workflow challenges if dealing with two channels, otherwise that would always be my go to for vocals and acoustic at least.
