I like nice side art, but its more important that the machine be fully functional and then if its feasible, I worry about the side art. Some machines like Starship 1, Missile Command, Joust, Space Invaders, and Sinistar have really nice side art that adds a lot to the game. For the most part I like to leave it alone unless its in really bad shape. That way the machine looks like its as old as it really is and is more original.
