Linux is probably more applicable to the future of UNIX than BSD.  It's
following POSIX very closely and all other OS are going that way too.
It's also very much like SysV and has most of the BSD stuff in it.

Also, SunOS is no longer a port of BSD.  It's yet another version of
SVR4.2 now, not BSD.  It's been that way since Solaris 2 was released
and it is the future, like it or not.

He wrote it following POSIX and standard UNIX so it's mostly the same.

Because BSD is dead.  I wish it were not so because I prefer BSD but
SVR4.2 is the future of UNIX, not BSD.  You actually made a wrong 
choice by your own critieria.

Anyway, the two are fine Unices so you should choose what you like best.
What you learn in either one is good for you and the differences between
the two are shrinking because SVR4.2 and Linux have most of BSD in them
and BSD is getting a lot of the stuff from SysV in it.  Like I said,
all OS are merging and your learning won't be wasted either way.

: Am I not putting enough faith in Linux? Too much in FreeBSD?

No, you just argued against yourself a lot.
