My mom always took her coffee black, so did my grandma, so I think it imparted onto me. For me I like the bitterness, when I take a sip of my morning coffee and it hits there's nothing like it.
Over the years I've tried to get into sugared coffees and I still keep coming back to black. Although every now and then iced coffee with creamer and sugar is a good treat.

To answer your question, for real: coffee is something I generally drink for caffeine content. Although every now and then, I might put some soy creamer and maple syrup, my main concern isn't taste. Even then, if the coffee is quality, black coffee's taste can still be very pleasing either way.
