FreeBSD is an easier desktop OS than OpenBSD. Supports lot's more out of the box, more 'modern' desktop environment, etc. Whether or not it's a better desktop environment is a matter of taste. OpenBSD is lighter weight, more uniform and more minimal. Old school. For some, that's better. I run OpenBSD on lower-end/older hardware (it runs awesome on a Thinkbook 42T or 43T), and FreeBSD on modern stuff.
