Since both Prologic and NEO:6 are both based psychoacoustic modeling, there's no best one. Even more so, you should pick the one that best models what you like to hear. If you prefer NEO:6, then that's the one you should use.

I prefer Prologic IIx, because I do have a 7.1 system, and I like what it does for the surround information extraction better than DTS's offering.
