I don't really drink too much hard stuff so I can't comment, but I'm with you on the beer. Definitely different types of buzzes for different beers, and I'd like to think it's more than just the ABV. For me, Hopslam would give me the most different buzz from anything I've tried (compared to like, an imperial stout with the same ABV). And although it's not my cup of tea, hard cider gives a different winey type of buzz as well. I mean, enough of anything will get you drunk though. But I notice difference between mellow buzzes and energetic buzzes. That has everything to do with the other ingredients, or what else you're eating and drinking then or throughout the day. The only variation in the alcohol itself is in how much is in the respective beers.
