Modules at initramfs are used for booting the system. If you use LVM,
Software RAID, encryption or a disk controller that is not supported
without a module, all those features require modules that need to be
loaded before mounting the root partition. Those modules are in the
initramfs.

Modules at /lib/modules/<kernel version> can be loaded when you plug
new hardware like a webcam or a pendrive.
