> Brangdon, the whole idea is: Slow Them Down, Calm Them Down.

Making a fire and boiling water is going to take a while regardless. As will drinking it when it is hot. I don't think the difference between tea and coffee will matter for this. For a calming effect it will be more important to have whatever it is you normally drink. "Normal" is good. I don't normally drink black filter coffee.

That aside, I wasn't so much commenting on whether quicker was better, but over whether tea was in fact quicker than coffee. I also doubt it is less dehydrating.
