Quick verdict: Midjourney wins 6-4 for most people. Midjourney V6 produces stunning images with simple prompts -- you don't need to be a prompt engineer. Stable Diffusion 3 is free, open-source, runs locally, and gives you total control with ControlNet, LoRAs, and custom models. If you want beautiful results fast, Midjourney. If you want unlimited free generation with full creative control, Stable Diffusion.
