Poor driver support, poor performance, lots of manual editing of config files to accomplish routine tasks, but BSD is "more cohesive" according to most of its proponents.
Matches exactly my annual experience of trying OpenBSD. It is not misinformation.
The FreeBSD handbook, for example, directs the user to manually edit wpa_supplicant.conf. If you want to switch from a static IP to a DHCP lease you need to run some commands as root and restart the daemon manually.
