FreeBSD seems to emphasise doing things right over doing them in a hurry and therefore may at times be a bit behind the curve in terms of support for the latest hardware and features. But when those features do come, they tend to be of superior quality (GEOM, Netgraph & bhyve for example) and rock solid. For serious server and and networking use (often in the guise of pfSense), that makes it my OS of choice. Glad to see some hardware vendors think the same way.
