So here are the results between different materials tests : beware, the differences are veeeery subtle ! But look carefully, you can see it.
Remember my goal was to get a porcelain material used in small hand-painted figurines.
So regarding what I'm trying to achieve, the best looking option I think is the "second sss skin".
The first skin is a plain white porcelain phong mat (well a blend of two phong mats as BbB hinted).
On top of that is a second skin, a sss medium blended with paintings.
The result is an insanely complicated multi-layered material, wich takes hours to clean !

The SSS Skin is amazing. Extremely convincing. But the thought of the render times makes my stomach hurt!
My idea about blending two phongs was based on copying this effect on the cheap. I.e. two layered materials with a slightly rough phong underneath (glossy reflections - exp. between 500-2000) and another phong (the coating, so to speak) on top with glass-like reflections (exp. of about 500.000).
Your SSS skin does just that but with three huge differences: It adds the tiny bit of scattering the coating would cause; it mimicks the slight translucency of porcelain; and the two skins give slightly offset reflections that are very noticeable on the smaller, sharper highlights.
In short: Great find!
PS: I wonder if it would be possible to fake the porcelain translucency by taking your diffuse map into photoshop, run a faint "diffuse glow" (or even "gaussian blur") filter, then mix this layer with the original diffuse map at 50 per cent...

Well I was afraid the render times would be huge, but that picture baked for 3 hours "only" (on a dual-core).
@5OnIt : A tutorial ? why not. There's no special techniques involved, it's more a question of spending time on textures, and blended materials (instead of using a single texture for the whole mesh). I'll try to make a quick overview of the workflow sometime.
