I almost always drink out of a tulip now. I feel like everything is better; aroma, fit to the mouth, and pour into the mouth. On occasion, for a big beer I'll drink out of a snifter. Prior to that, I used to drink out of pint glasses all of the time.
I've never liked drinking out of anything that was tall, like the 23oz glasses, because the beer had too far to travel, and ended up picking up way too much speed on the way to my mouth. I never cared for mugs either because the glass just felt way too thick.
