Having driven and degreed most of the factory VE camshafts, I would rank them in the following order for low end power.
1. 20V best
2. N1
3. 20VE
4. 16VE
Keep in mind there isn't a large difference between them, we are talking about the lowend after all.

I guess not one person read the numbers I put up there or the dyno graph that another member put up there.
There is almost no difference, down low, where it would matter for a daily driver, between the two cams. Let's say your switch point is 5200 RPM, you really will not see that more than twice DD'ing like a civil person.
The only difference you will feel is the car will peak earlier and begin to get slower earlier than a car with N1 cams.
The illusion that they are better is masked behind this concept.
It is best to have an exhaust cam larger than the intake cam to promote scavenging. The only VVL cams to do this are SR16VE cams. What goes in, MUST go out. Leaving the gases inside the engine does nothing good, period. It is wasting time, air, energy when you could be making more power.
20v cams were designed around a 6 speed gearbox, remember this.
I don't know why you have such a strong opinion about this subject when you know you have no first hand experience.
I will point out one major contradiction to your statment about the 16VE being the best because of the scavenging. In reality, it's has one smallest low camshafts. The intake is the smallest of all the camshaft. Since scavenging require the intake and exhaust to be open at the same time, how is that possibile when the 16VE has 0*overlap.
