What are some flavored liquors that are tasty enough to drink straight from the bottle or without a mixer?

I do generally like wine and some beers like Guinness. But as for liquor, the only stuff I’ve had is Jack Daniel’s and Makers Mark. But drinking them on their own/straight is just not very tasty to me. I started with making Jack and Coke but then found they had flavored ones like Winter Jack, Fire and Tennessee Apple. All of those I really like.

So I’m curious what other flavored liquors, whether that’s whiskey, vodka, gin, or something else, I could try that could preferably be found at a Find Wine & Good Spirits.
