Not that I would be able to help you here, but what are you looking for? What do you want do to/acheive. A little more background information will help get the advice you need/want.
Ubuntu - easy to use/install software/maintain. Wide user-base means lots of support. Cloud support out-of-the-box with the latest version. Will be slightly slower than FreeBSD. Power has been slightly sacrificed for ease of use.
FreeBSD - not as easy to use, but definately one of the best server OS systems out there. Some incredibly large servers serving up tb's a day run on it with little problem. It also has some of the greatest minds in networking developing for it, and has the best networking drivers of any OS I have seen to date. Problems with it are the fact that it is a little difficult to use compared to other systems, and not quite as user friendly.
I've heard that FreeBSD is very good at serving databases (file i/o and networking being pointed out specifically) when compared with serving from linux. I'm yet to prove it (and sounds like there may be a chance for that in the mid-term) - but, some hunting around on the internets will find benchmarking results et al.
