Assuming, of course, that you purchase the Sun compiler.  I certainly can't
afford their compiler, unless it's cheaper on disk space and the wallet than
it was.

Clear Solaris wins out here, I'm sure that the scheduling things are
somewhat crude on Linux.

As an enterprise system, who cares?  Solaris is able to do a lot more with
that ram.  As a desktop, perhaps it's an issue, but with 256MB of ram, it
shouldn't make any difference at all.

I suspect that for servers, Solaris is going to win every time, unless it's
a really old machine.  Certainly for any Ultra machine, Solaris is going to
be nice.
