Pick Model A if you need a single, versatile zoom covering wide to super-telephoto and can accept the slower aperture at longer focal lengths. Model B stays the better choice if you prioritize faster f/2.8 performance, sharper optics, and lower weight within the 70-200 mm range, especially at its lower used price.
