Which to pick

Pick the 7Artisans 18mm f/6.3 II if you want a design for APS-C, which usually means smaller and lighter. Pick the Viltrox AF 28mm f/4.5 if you want a brighter f/4.5 (1.0 stops more light), for dim light and softer backgrounds; autofocus; and coverage of full frame, so it suits the larger-sensor bodies too.
