Which is better MVC or MVVM?

Conclusions. Both MVP and MVVM do a better job than MVC in breaking down your app into modular, single purpose components, but they also add more complexity to your app. For a very simple application with only one or two screens, MVC may work just fine.

Why is MVP better than Mvvm?

The advice hides rather in data-binding. In cases where binding with DataContext is not possible, most developers prefer MVP (Windows Forms being a great example). MVVM is of preference in cases where binding with DataContext is possible, as there are less interfaces and less code to maintain.
