We went with laminate because we got tired of trying to protect the carpet. We wouldn't walk in the coach with street shoes and generally speaking the carpet still showed a path where we had to walk. Despite all our efforts, when I pulled the furniture out the carpet we though was clean and well protected by our efforts was actually soiled.
Now that we have been living with the laminate it has been a real easy floor to live with. A damp mop or a quick pass with the vacuum does the job of cleaning and if there is a difference in noise level I cannot tell. We have two throw rugs to break up the and expanse and out future redecorating will be a visit to Wal-Mart to buy two more of a different color or design.
