I have the 99 learning relay in the 3.2 and traditional dial setup in 2.2.
I prefer, by miles the 2.2 - I find the 3.2 fine on first set. It's re-adjuating it in changeable conditions, I find the 2.2 far better with the dial for a quick change. Rather than cancel, flick, count and set. Just adjust the dial 
Where as the standard rain sending wipers. One click, job jobbed.

But we all know the original variable intermittent wipe system is far better than the schoolboy first attempt GM slapped on the later Omegas....
The fixed delay intermittent wipe fitted to my 1994 CD was more useful than the random wipe (optimistically called "rain sensitive") fitted to my 2003 Elite 
Ah but that's where your all completely and utterly wrong, because, you haven't cleaned your screen properly. Behaves perfectly, just does. Accepte it, deal with it, and move on. But remember...
....clean your screen. Especially where the sensor is. Obviously.

Nope, we all know you are completely and utterly wrong. The system fitted to later Elites is poor. Almost like it was an early prototype to learn from for later cars.
See, from posts above, lazy bloody admin again. CLEAN THE DAMN SCREEN. 
And by clean I don't mean waft a rag over it, I mean clean until a clean cloth comes off clean with no marks on the cloth itself with a proper glass cleaner. Also be weary of machine washes and Hungarivanians magic cleaning potions. They leave residue the sensor sees and tries to wipe off.
If honest with ones self, you'll see said residue on the screen anyway. WONT YOU JAMIE

Glass polished inside and out usually weekly.
The issue with the pieces of shit useless rain (inability to) sense wipers is even by my standards, they are hopelessly slow to see rain to begin with, so you have to turn them off and on manually to get them to start, after which they go into ful turbo mode if there is a mist drop at 500 paces.
Hopeless.
And every time I use it in the rain, I remember why they are such as step backwards from the adjustable intermittent type.
That's the advantage of having both types, it highlights the shit parts from each
