I need to choose between making a bunch of sub-sites or site collections.

A Site Collection in SharePoint is basically a collection of SharePoint sites that share common features like Content types, Templates, Site columns, permissions, Web Parts etc.

  3. Unique set of workflows, site content types, site columns
  4. Unique quotas

Single site collection with Sub Sites
