Too broad question. Simple answer poluquaternium. Reasonable answwe: depends onb your formula and desired results.

In my opinion, silicones leave a noticeable, smoother feel than polyquaterniums do.

But most silicones need expensive solubilizers, or complex suspension procedures.

While polyquaterniums just need to be poured in and mixed.

@Gunther, that might be my experience but I think silicones perform better as leave in products. Maybe I have to rethink it. How much of dimethicone would give noticeable effect as per your experience?

I did not know that silicone needs a solubilizers if not

I chose the poly without asking my question!

Polyquat 7 and Polyquat 10 are commonly used ones. Keep in mind that 10 is derived from hydroxyethyl cellulose which is a thickener. If you see lumps in the finished profuct just leave it overnight.

This study hints that quats/polyquaterniums might increase silicone deposition.

A preliminary investigation of the interaction of a quat with silicones and its conditioning benefits on hair.

But there are some limitations to be aware:
1 It used Tricetylmonium chloride (Varisoft TC-90 ), instead of common use Polyquaterniums 7 or 10.
2 It was a semi leave on study as they dipped in test tresses, squeezed them to remove excess liquid, but were NOT rinsed.

I agree silicones will give a more noticeable results but Polyquaterniums are much easier to formulate with.
