It kind of depends on what you are looking for in your coffee.
Do you drink espresso, ristretto, lattes, capps?
What machine/method are you using?
What beans have you tried?
Were they pre-ground?
Do you know how old they were?
Some beans will have flavours that are subtle and lost in milk.
Also, a beans flavour profile changes depending on how they are roasted.
Sorry for so many questions, but it will help get a better answer for your personal quest.
I sound like an RPG again!
