Sony 400-800mm - OVERPRICED or PERFECT Lens for BIRD Photography

Is the Sony FE 400-800mm f/6.3-8 G OSS much better suited for wildlife photography than the Sony FE 200-600mm f5.6-6.3? Is an upgrade worthwhile? What about autofocus and sharpness? Or is it too heavy and inflexible? I share my first impressions in this video.
