I've been using LUKS for full disk encryption on all my computers for many years. The main benefit is that if someone steals my computer, they don't get access to any of my personal data (unless they are very smart or have a $5 wrench). The main downside is that every time I reboot my computer, I have to type in the disk encryption password so it can actually boot.
