For the centre, I like full extraction. When I hear a human voice produced in real life, it doesn't sound like a dual-mono comb-filtering phantom image, instead sounding like a mono point-source. When when I listen to vocals re
produced at home, I prefer to hear them as mono point-sources, just like I do in real life.
I'll admit I'm in a minority when it comes to centre extraction. A friend who orignally worked on PLII likes to extract just enough centre output to ameliorate the normal comb filtering you get from 2-speaker playback. This ends up spreading centre content evenly to the L/C/R speakers (1/3 to each). Since I'm not a fan of dual-mono playback, I like triple-mono even less, hence the full centre extraction. But most people I know like to set the centre extraction somewhere between full and phantom.
I use my surround processor 90% of the time to listen to 2-channel music in surround (been listening that way for almost a quarter century). Movies are a distant second priority. With that in mind, I like to dial in the surround extraction so that it widens the soundstage but doesn't sound like surround sound. It's subtle enough that it never calls attention to the surround speakers. Most people that visit don't realize I'm using surround processing until I turn it off and the soundfield collapses to the front soundstage.
So, full centre extraction, subtle surround extraction. YMMV.
