Feature layers can be created by referencing a layer from either a map service or a feature service or by specifying a feature collection object. Use a map service if you just want to retrieve geometries and attributes from the server and symbolize them yourself. Use a feature service if you want to take advantage of symbols from the service's source map document. Also, use a feature service if you plan on doing editing with the feature layer. Feature layers honor any feature templates configured in the source map document. Feature collection objects are used to create a feature layer based on the supplied definition.
