Verdict
Pick Model A if you need the extra reach for wildlife or sports and can accept the slightly dimmer maximum aperture and heavier build. Model B stays the better choice if you prioritize a wider starting focal length, constant f/4 aperture, and lighter weight for run-and-gun video or general-purpose shooting. Both share the same budget, so the decision hinges solely on focal-length needs and handling preferences.
