It's transparent for end user basically, but protects the laptop at least when outside and if someone steals the computer. As long as it was properly shutdown.
Define properly shut down. Do your thieves usually ask first?
I think they're just referring to an outdated concept of OSes with non-journaling filesystems that can cause data corruption if the disk is shut off abruptly, which in theory could corrupt the entire disk at once if it was encrypted at a device level. But FDE was never used in the time of such filesystems anyways.
If you suspend the laptop when moving locations instead of shutting down or hibernating to disk then disk encryption is useless.
Most operating systems will require your desktop password upon resume, and most thieves are low-functioning drug users who are not about to go Hacker Man on your laptop. They will most likely just wipe the system and install something else; if they can even figure that out.
