I prefer getting whole bean and grinding/brewing myself.
That said, I like Starbucks Sumatra. AND before you jump on me about Starbucks, let me say: You can't beat it with a stick. Dunkin is bitter, MacDonalds is crap, Horton's is thin, blah blah. I like the consistency of Starbucks. I've sampled them all, many times, and it ranges - in the same store - from thin & weak to too strong, bitter or burned. Starbucks is good, I buy it, I know what I'm getting. Even local coffee houses, around meat least, can't make it consistent.
