Cardigans would absolutely win the award for “most versatile sweater”.

This meta-pattern is offered in sport, worsted, and bulky gauges. The samples were worked up in vintage, casual, and classic styles. Customization options include different closures (open, tied, buttoned) and stitch patterning (bamboo-like ribbing, lacey ribbing, and seed stitch stripes).
