Prompt
"A 20s woman with wavy dark-brown hair in a messy bun, wearing an oversized oatmeal hoodie and black leggings, holds a minimalist stainless-steel insulated water bottle (logo facing camera) while taking a casual phone selfie in a bright kitchen with a clean white countertop and light backsplash. She’s looking near the camera with a relaxed half-smile, one hand on the bottle and the other holding the phone, natural morning window light with soft shadows and catalog-clean clarity. Include a “multiple angles” feel by showing the bottle once in her hand and once set upright on the counter in the same frame, like a Shopify/Amazon lifestyle listing but still UGC-authentic."

Verdict
If your priority is premium, ultra-polished e-commerce visuals—especially hero product-on-model images where fine texture, lighting realism, and a high-end finish drive perceived value—Flux Ultra 1.1 is the stronger pick, though it comes at a higher per-image cost (16 credits).
If you need scale, iteration speed, and flexible workflows (including image-to-image) for building large catalogs, testing variations, and refreshing store imagery efficiently, Grok Imagine offers better value at 4 credits per image while still delivering convincing photorealistic results.
