Aquestion about base page class and templating

I have created a base page class to handle templating. In this page class i
have added panels (to render the divs for the css based layout),
genericcontrols and literals to create the page. Is it efficient to use
controls for the different parts of the layout, or is it better to use a
direct write where possible and use controls where variable content (that
changes from page to page) is needed?

Thanks...
