Paint or wallpaper over concrete wallas?

so i started my kitchen about 2 maybe even 3yrs ago. knocked down a wall where it used to be a pantry/laundry rm but i wanted to open up the kitchen and more privacy but all i got done was the floor and even that isnt really even. but the walls are concrete and may need some spackling. would it be better to just slap some wallpaper on or paint them?
