The distributions contain kernel code that is heavily tested and stable, =
in addition to a toolchain, debuggers, rootfilesystem, etc.  =
git.xilinx.com is just the kernel code, without anything else.  =
git.xilinx.com also contains new code that is under development, rather =
than primarily stable code.

'better' for what?
development of new code? yes, most distributions use older kernels.
building a sytem? Maybe... it depends on what features you need.
learning? Maybe... It depends on what you already know and what you want =
to learn.
