a "strange" question about OSs

[Valentin Bud]

Hello Community,

 The following question may sound very ackward but was OS is suitable from
the following list
to replace FBSD:

   - OpenSUSE 10.3
   - Debian 4.0
   - CentOS 5

The company i work for wants to change the provider because of the
economical crisis to
save some money. The actual provider gave us the chance to install our OS
but the one
they chose as a replacement doesn't give any other choice besides the above
mentioned.

I work for 2 years in IT and FBSD is the only OS i have ever used in
production. I like it and
learned it a little bit. It is going to be a steep learning curve with the
new OS which I'm not afraid
of but i would like to chose a suitable OS and one that has some
similarities with FBSD.

thank you,
v
