There are several important differences to note. Linux is really just a
kernel - each distribution has it's own idea about what software to
include,
so there are several different distributions with subtle differences
between the two. The Linux kernel was developed essentially from
scratch.
FreeBSD is different. It is based on the 4.4BSD lite code developed at
the
University of California at Berkeley. The BSD code is is time-tested
code
which has been the basis for many commercial Unix implementations, one
of
the most notable being SunOS 4.x. Unlike Linux, FreeBSD (and indeed all
BSD-based OS's) is a complete OS. No matter where you obtain FreeBSD
from,
you will get the same OS. All of the freely-available BSD OS's are
practically
identical - there is a lot of code sharing that goes on.
Both are developed in a more-or-less open development environment, in
the
sense that both are source-available, and that fixes and enhancements
from
non-development-team members can be integrated. In this regard, they
differ
in the Linux kernel is controlled by a single person, and the entire
FreeBSD
OS is developed by "committee".

It really depends on what your requirements are. In my opinion, if your
hardware is supported by FreeBSD, and the applications you wish to run
will run on FreeBSD (you can run Linux binaries on FreeBSD, by the way),
you might be better served by running FreeBSD. The reason I say this is
for two reasons- one, FreeBSD is more stable under load than is Linux.
The other reason is that since there is a single FreeBSD distribution
which is professionally developed, you are not dependant on the vendor
for
distribution-specific problems which may occur. The only disadvantages
are that more people run Linux than FreeBSD, and due to this, support
for new devices tends to be added to Linux first. (just because more
people run Linux than FreeBSD doesn't make it "better". After all,
more people run Windows 95 than Linux...)

This is somewhat true - I can't really comment on Linux in this regard,
but
I do know that the FreeBSD developers can only add support for devices
that
they own, and most of them don't buy inexpensive and non-standard
hardware
for their own use. For example, it took quite awhile for good ATAPI
CD-ROM
support to be developed, because none of the developers had (or wanted)
an
ATAPI CD-ROM drive. This coupled with the fact that MANY drives don't
really
conform to the standard made it difficult to develop good drivers that
work
on almost all of the drives available difficult to impossible. Only
after
some kind soul donated a large box of ATAPI drives was someone able to
make
real progress.
This is often how support for a device is done for FreeBSD - someone who
wants it either writes it, or donates the hardware and convinces one of
the
kernel developers to do it for him.

Difficult to quantify. This is more a function of the compiler used,
and how
well it optimizes. I can say that in general, FreeBSD and Linux
multi-task
_much_ better than DOS/Win31/Win95.
