Verdict
Pick Model A if you need the extra telephoto reach (250 mm) and can accept a slightly slower aperture at the wide end (f/4). Model B stays the better choice if budget is tight, a wider starting focal length (18 mm) is more useful, or you prefer a lighter setup—just be aware of its shorter zoom range and variable maximum aperture.
