Zola is the best IMHO because it combines a single binary, expressive templates, runtime speed, and batteries included for images, sections, tags, search, links, microformats, and deployments. Zola also has excellent documentation, clarity of design, and a highly motivated leader in Vincent Prouillet. Rust lends itself very well to SSGs.
