The first un*x I've ever installed was FreeBSD. At the time I didn't have internet at (my parent's) home and had to rely on the CDs and the user manual. To this day I think it's the best introduction to the Unix world I could've had. All the documentation is great and since the BSDs are somewhat more monolithic than GNU/Linux distributions it's very well self-contained and coherent. After a day of work I went from formating the hard drive, bootloaders etc.. to having a full blown KDE environment. And I knew how everything worked underneath. It truly felt like an achievement. And that's how I became a loyal FreeBSD user.
