Personally, I am torn between what I like visually and what I find appealing to sit in, and welcoming for guests. Visually, I like very clean, austere designs. But I know that many of those are not comfortable to sit in, let alone flop down in to have a lazy nap. Ideally my perfect design would look very simple and neat, but still invite people to flop down. I hate loose-pillowbacks and long sofas with two main cushions (makes the center position useless as no one wants the crack), and also dislike tightbacks in general. I like the look of wood arms or no arms, but I know those are not comfortable. I was surprised after finally sitting in the Barcelona how comfortable it actually is, considering how clinical and hard it looks.
