3 link vs triangulated 4 link - Why is one better?

[68454RS]

I know this has been discussed before, many times BUT, talking performance only, not cost, not installation, just performance, triangulated not lateral 4 link.
... I keep hearing the 3 link is so much better than a triangulated 4 link for auto-x performance and I don't understand why. If you take both set-ups and add the ridetech "R" joints on all ends, you would not have any binding, IMO, So,

4 link with all ridetech "R" joints
3 link with all ridetech "R joints

The 4 link would not have any binding, correct?
The 4 link would control any side to side movement, correct?

The 3 link would allow the rear to move side to side slightly with articulation due to the track bar, correct?

So what makes one better than the other?

I did put the complete Ridetech R joint kit in my Camaro and the articulation was just as Brett showed it in his R joint videos. My FFR 33 has the option of doing either and already has the 3 link bracketry if I want to go that route. I already have all the 4 link set up with all R joints. Remember that money is not the consideration here, strictly performance. What would I gain going to a 3 link?
