I use OpenBSD on my laptops and desktop. The KMS drm drivers have been improved for 5.6. So you have 2D/3D acceleration, and unlike with FreeBSD, Xorg just works without configuration out of the box. For a more "desktop" experience, OpenBSD 5.6 also has working GNOME 3.12.2. One thing that tends to trip up desktop users is the default ulimits, BSD has login classes which may need to be tuned in login.conf(5). This is especially true if you plan on using modern web browsers which are resource hogs.
