Glace vs Hypnotica

Glace was the first mone I brought(FB Sillicone), but I think I never bothered to ask this question on the forum.

Which one is better?

I am planning to buy the original slow burn Glace next, but I also would want to try Hypnotica. I still got a full sample vial of it, but I don't think it would do justice in terms of comparing the effects. Unless all I needed for Hypnotica to work is 1-4 drops, which would last the sample long enough for me to buy it.

I know FB Sillicone Glace need at least 3 sprays to work, what dosage does the original slow burn version need? What dosage for Hypnotica?

thanks in advance.
