There's no difference in the engine, but I don't trust Chessbase's UCI
implementation. When initialising UCI engines the GUI sporadically fails to
allocate the requested memory for hash tables. UCI engines are at a disadvantage
in engine tournaments at short time controls, because the clock starts before
the initialisation is complete.

But even if Chessbase's UCI implementation did work correctly, it's a matter of
principle. There's a high quality engine being tested by CSS - a magazine that
has close ties to Chessbase - which has never been made available to the public,
as far as I know.
