Which is stronger for image generation, GPT or Grok?

The former GPT, the latter Grok

Prompt: Create a dramatic black-and-white portrait with a melancholic cinematic atmosphere. Use high-contrast lighting to outline facial contours with deep shadows and bright highlights. Make the subject appear moist, as if just drenched by rain, with irregular water droplets and streaks on the cheeks, forehead, and jawline. The hair should look wet and slightly tangled, with a few strands naturally falling on the cheeks. Keep the background dark and minimalist to emphasize the illuminated facial features and water droplets. The overall effect should be tense, emotionally rich, and photorealistic—an original portrait with realistic rain textures and dramatic tonal depth.
