下面两段代码，你认为那一段写的更好？

下面2段代码的功能是一模一样的，但写的方式不一样。你更喜欢那一段呢？为什么？

代码1：

1 public ActionResult ApplicationDetails(long applicationId)
2 {
3     var model = new ApplicationDetailsViewModel(applicationId)
4         .BuildPhones()
5         .BuildEducationHistories()
6         .BuildReferences()
7         .BuildWorkHistories();
8     return View("../EmailViewer/ApplicationDetails", model);
9 }

代码2：

 1 public ActionResult ApplicationDetails2(long applicationId)
 2 {
 3     var model = new ApplicationDetailsViewModel(applicationId);
 4     var builder = BuilderFactory.CreateBuilder<ApplicationDetailsViewModelBuilder>();
 5     builder.BuildPhones(model);
 6     builder.BuildEducationHistories(model);
 7     builder.BuildReferences(model);
 8     builder.BuildWorkHistories(model);
 9     return View("../EmailViewer/ApplicationDetails", model);
10 }
