The flexibility and stability of a UNIX system is what's great about FreeBSD. I used to use it while in university, and I enjoyed it a lot, however, it has its downsides as well, such as software compatibility, etc. which I think must have improved a lot since then.

Not so great compatibility with various software. You need to go out of your way to find the software that is compatible with the OS, however, this has improved in recent years, and also it depends on what you want to use the OS for. Review collected by and hosted on G2.com.
Stability: FreeBSD is known for its stability and reliability. It is designed to run for long periods of time without crashing or requiring a reboot. Review collected by and hosted on G2.com.
While FreeBSD has a large collection of software available through its ports system, it may not have as many software packages available as some other operating systems, such as Linux. Review collected by and hosted on G2.com.
