It is difficult to determine which version of Midjourney is the best as each version has its own unique features and capabilities.
- Midjourney V5 is the latest version and is known for its photorealism, but there are still some kinks to be worked out.
- Midjourney V4 and V5 are not meant to compete with each other, as they cater to different needs.
- Midjourney V1-V3 produced psychedelic and strange artwork, while V4 and V5 produce high-quality images that can be used in a variety of applications.
- Ultimately, the best version of Midjourney depends on the user's specific needs and preferences. But most probably you best always take its latest version.
