This is a really interesting post!

I have medium-thickness hair, with medium porosity. I almost never tangle, and if I do, it's never bad. But I MUST have the highest slip possible. If it's even the slightest bit grabby, my hair loses all wave definition, sticks to itself, and turns into a giant, frizzy mass. Slippery condish smoothes my hair out and calms the frizz.

Also, grabby conditioners tend to leave a sticky film on my hair, regardless of how little I use.
