I will be interested in your experience switching to freebsd
In FreeBSD you have the same packages included as a debian, even more, and also updated to the latest version, it is the ports system.
The ports system is maintained by FreeBSD and volunteers and is also adapted to the rest of BSD flavors so you will not have software problems, basically all Linux software is available in BSD.

I have always used both, there are times when I have lost interest in one and have returned and vice versa, although in my profession I have used both.
