Well I'm partial to Johnny Walker Gold, as mentioned previously. Super smooth for being a whisky. No real burn to speak of. And it gives you that euphoric drunk. Not the low stupid drunk of cheaper liquors or beer. Everything feels more crisp. Somewhat similar to wine or champagne, but better.
If you're not looking to get drunk, but just want to relax with something that tastes good, then something like Mike's would be good. Or Smirnof Ice. I used to drink that all the time. Haven't seen it in a while.
