I like the built in as it provides storage as well as a counter to use when entertaining. I don't like the symmetry of both the top and bottom being the same width.
I like the interest that the wall unit adds since it's not the traditional lines.
I like the credenza because it has some height to it.
I like the style of wall clock. This could work in the living room.
Like the buffet. Doors to hide items and one open shelf for contrast.
