Verdict
Pick Model B if you prioritize a brighter f/2 aperture and lighter weight for low-light or shallow depth-of-field work, especially within the 28-70mm range. Model A stays the better choice if you need the wider 24mm starting focal length, longer 105mm reach, or image stabilization for handheld shooting. Both share the same price, so decide based on focal range and aperture needs.
