Developing the interface of a website is hard. You never realize how many little details go into a single web page until you try to code one yourself. Coding the backbone of a website is much better; it's straightforward work and not nearly as much tweaking or browser compatibility to worry about.

Then again... I tend to be lazy when creating my own content management systems and just grab a premade one, like Drupal, which cuts down the amount of coding I have to do (and interface modifications). Then all I have to do is focus on content.

As to the original question, developing standalone applications is far more enjoyable for me. They're faster to run, easier to create, and overall a lot more straightforward in the development process.
