I've used the Pro-Grip - did the job, but the one I had had a black rim which was annoying.
I've used the Pro-Grip photocromatic - only changed in direct sunlight, so glare was still a problem and I needed sunnies
I've used the Fog-City - it was very fumey - ie it stank.
Spit doesn't work.

I don't have anything on my current visor - I crack it open a notch when not on the freeway, even in the rain.
If fogging becomes a problem I just start blowing air down out of the helmet rather than breathing out as normal.

Interesting article on the object of your discussion here

Comparison between ProGrip and FogCity visor inserts, and also discusses the photochromatic properties of each as well.

I used to use a product like Rain-X, but for the inside, not the outside - I think it was called Fog-Off or something like that........

Most new lids these days have effective venting around the mouthpiece/chinpiece area, that will stop any fogging - I know my old Shoei does, and it works *just fine* for normal riding. In the rain, it needs to be opened the first half-notch, thats it.
