Pick Model A if you prioritize a brighter maximum aperture at the telephoto end (f/5.6 vs. f/6.3) and slightly lower used pricing for a standard zoom range. Choose Model B if you need the extra reach to 250 mm and can accept the dimmer telephoto aperture, especially since it costs less. Model A stays the better choice if you shoot in low light or prefer a more compact, lighter lens; Model B wins if versatility and budget are your top concerns.
