What tag to use? : Suburb or Neighbourhood?

Hi there, i have the following

If you navigate to the government site of Erbil - Iraq : http://hawler.gov.krd/en/maps.php and click on “Map 2”
You will see The City Erbil dividid in multiple areas.

What tags should i use Suburb or Neighbourhood?

Because if i use the tag Neighbourhood, I can mark the outline of that region, but the Tag Suburb is just a single tag.
