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：

public ActionResult ApplicationDetails(long applicationId)
{
    var model = new ApplicationDetailsViewModel(applicationId)
        .BuildPhones()
        .BuildEducationHistories()
        .BuildReferences()
        .BuildWorkHistories();
    return View("../EmailViewer/ApplicationDetails", model);
}

代码2：

public ActionResult ApplicationDetails2(long applicationId)
{
    var model = new ApplicationDetailsViewModel(applicationId);
    var builder = BuilderFactory.CreateBuilder<ApplicationDetailsViewModelBuilder>();
    builder.BuildPhones(model);
    builder.BuildEducationHistories(model);
    builder.BuildReferences(model);
    builder.BuildWorkHistories(model);
    return View("../EmailViewer/ApplicationDetails", model);
}
