For me, the best thing about Leonardo AI is the ability to create quite good images with free plans and the number of customizable parameters you can work with to generate images.

Leonardo.Ai offers full ownership of generated content, with full rights staying with the user. Non-expiring API credits support long-term planning. It also enables custom model training and fine-grained project permissions, making collaboration across teams with varying access needs much smoother.

It is a very good accomplice to work and tries very hard to make work easier in terms of Art support.
