I've been generating AI images daily for the last year — probably 4,000+ images across multiple platforms. Two of the tools I keep coming back to are ZSky AI and Midjourney. They're built for different people and they make different trade-offs, but the comparison is interesting because they overlap in the middle: hobbyists who want good images without learning Photoshop.

This isn't a "Midjourney is dead, switch now" post. Midjourney is genuinely excellent at what it does. But it costs money, and ZSky doesn't, and the quality gap has narrowed enough that the math is no longer obvious.

Here's the honest breakdown.
