How would you compare the reliability of skullcap as a sleep aid compared to valerian, hops, or chamomile?

It turns out that valerian is not the right fit for me after trying it on a few different occasions. It reliably puts me in a headapace that is equally sedating as it is anxiety inducing.

On the other hand, chamomile seems to take the edge off, but not quite enough to steer my mind into relaxation.

Hops is pretty reliable in bringing on a heaviness that can be used for relaxation and sleep.

I keep seeing skullcap recommended on here for sleep. How would you compare it to the others mentioned?
