Verdict
Pick Model A if you prioritize a brighter maximum aperture for low-light shooting and sharper image quality at the wide end, or if budget is a key factor. Model B stays the better choice if you need a versatile all-in-one zoom range for travel or situations where swapping lenses isn’t practical, despite its dimmer aperture and higher price.
