Verdict
Pick Model A if you need the extra reach (400 mm vs 300 mm) and a lighter, more compact telephoto zoom for general wildlife or sports. Model B stays the better choice if you prioritize a constant f/2.8 aperture for low-light performance and shallower depth of field within its 120-300 mm range.
