No, especially considering that USB is one of the worst offenders in the
"stops my notebook from going to sleep" group and the best way to work
around that is to unload the USB modules.

The only benefit you'll get is that you won't need an initramfs image to
boot and the value of that's debatable. And if you ever want to use
uswsusp you'll need an initramfs image anyway.

If there is any difference I guarantee it'll be so small to be well within
the margin of error of any benchmarks.
