Question about event handling

Let's say I use SDL (1.2 or 2.0) in my program to handle events, should I use callbacks or the good old giant switch statement?

Also using a for/while that calls every callback that may not even be needed

Why would you even do that? Do you even know what a callback is?

And why are you microoptimizing before profiling? I bet you're going to use dynamic linking, killing any LTO you might have gotten.
