Yikes! Plastic is worse than landscape fabric. Totally seals out air and water exchange and eventually degrades into little pieces. What are you planting? What sort of weed problem do you have? What kind of mulch is your landscaper planning to put down? If it's a definite choice between the two, go with a professional grade fabric, not that flimsy black stuff. If you don't have a major weed issue, just mulch and occasional maintenance.
