For me, it depends on my mood and how much attention I want to spend on enjoying my drink. Dunkin Donuts is my everyday brewed coffee. Their coffee is consistent, predictable, plentyful and they have lots of locations with drive-throughs. The flavor is distinctive and I like it, but it's not distracting. I choose it when I want something hot but want to keep my mind on other things -- driving, attending meetings/phone calls, reading/writing for work, keeping deadlines...

If I have the luxury of time to focus on the coffee, I'll go out of my way to get Starbuck's or better. Something strong and bold which will call my attention at each sip.
