I have a few reasons.
I find not having to install daemon for this better. The kernel
already knows how to handle this and it does it well. Also some of
these daemons cause improper frequencies to be set and reported
through /proc/cpuinfo. And finally using the in kernel setup allows
the same simple boot configuration for any amd or intel cpu. That
assumes the proper modules are activated in the kernel.
