Like asking absolute best flavor of ice cream. You have to keep listening and find out which sounds best to you.
Having said that, I use Logic7 processing that others mention, but that mode is likely not in your receiver. Of the two most popular surround processing modes, I pefer PLIIx over Neo:X because it is more directional in the surround field.
As BIslander said, PLIIx extracts stereo surround-back channels while Neo:X extracts a mono surround-back channel (which is sent to both rear speakers).

Yup (eight years before PLIIx).
