The Configuration.cs Seed method will run every time your model changes to make sure that some specific data stays in your DB, or to even possibly to reset that data to a specified default setting.

The Custom Initializer's seed method, on the other hand, can be setup to run every single time the application loads, like in this code, which is currently in the Global.asax file of my MVC page:

Database.SetInitializer(new MyCustomInitializer<MyDbContext, Configuration>());
var db = new MyDbContext();
db.Database.Initialize(true);

The practical difference really comes into play after you deploy your application. The Custom Initializer will make sure that no user can destroy some data that's absolutely required in your program.
