I use both L'art du Son and AIVS 3 step on my PRC4. L'art du Son is very effective in both time and quality of sound, so I use it most of the time. AIVS definitely provides better sound, but is much more time consuming (15 min a side or so, assuming you stay on the ball) so I tend to save it for really good recordings that I listen to on a regular basis.
Incidentally, I did quite a few A/B/C expts. when I still had my last RCM. In my experience, the improvement of the Loricraft over my last RCM was literally orders of magnitude larger than the difference between AIVS and L'art du Son.
