In our previous home, when running just 3 front DSPs, I normally found myself using Ambisonic most of the time, occasionally Trifield. I found that Direct and Stereo (had a 568 back then) were somehow flat by comparison.

Ambisonic in particular had tremendous space & air to its presentation; not everyone may like that of course but it was my DSP preset of choice.
