It is.

I think everyone working on it does, in the sense that lldb should
include any functionality that's useful in a debugger, which
presumably will be a superset of current gdb features.

Beyond that I can say that on one platform (Mac OS X using clang 3.5)
where the available gdb throws so many <optimized out> values for
function arguments and local variables as to be nearly useless in
debugging code optimized to the production configuration, lldb usually
can tell actual values and is thus much more useful.  I can't say
whether this extends to GNU/Linux as I only use gdb there, although
the frequency of <optimized out> is indeed a PITA on GNU/Linux too.

Ah, it appears that a reasonably recent gdb has appeared in MacPorts
since I last checked.  I'll have to try that.
