Drivers compiled into the kernel can be compiled with specific options, and they make debugging easier in case of a panic (provided you get a dump). Some drivers fail to initialize properly if they are not loaded at boot time (i.e. compiled into the kernel *or* enabled in loader.conf) and of course some drivers (such as those you need to access your root partition) *must* be present at boot time. Leaving drivers out of your kernel config saves some compilation time, since unless you tweak MODULES_OVERRIDE to only build modules you know that you will need, everything in your kernel which is also a module gets built twice.
