I don't think you can say one is better than the other - it depends what you are doing.

There is a detailed overview of context switches here: http://en.wikipedia.org/wiki/Context_switch

In the most basic sense a context switch is when the processor pauses execution of a task to do another task.

Also, you have to remember that threads may be your only choice if your OS is embedded and doesn't support multiple processes ;)
