I would get both. They only last a year or two if you have a strong dog/puller. The plastic material wears out (check daily) and make sure that the harness fits snug.
See if you can find something in leather, it will last longer.
Another thing to consider, I would get a Nifti Leash, my terrier likes to roll around on his back and is able to get the standard clip style leash to disengage and off he goes! http://www.niftisafelatch.com/shop
