small size and low weight
better build quality than the price suggests

Main competitors are the Samyang 18mm 2.8 AF and the Tamron 20mm 2.8. Considering this Viltrox is by far the cheapest of the bunch I think it compares favourably to the other two, but none of these lenses is perfect, so depending on what you are looking for, you may prefer one or the other.
