Pick the Sigma 18-200mm if you need a single, versatile zoom for everyday shooting—from wide landscapes to distant subjects—without changing lenses. The Tamron 10-24mm stays the better choice if ultra-wide angles (10-18mm) are critical for architecture or tight interiors, or if you already own a telephoto lens. Budget is nearly equal, so decide strictly on focal-range needs.
