Your Opinion about Jean-Marc Baillard's RNGs

[ttw]

Just looking quickly leads me to guess that program #2 is best. Which number to use for the multiplier depends on the continued fraction expansion of that multiplier and 9,999,999,967. One with smaller partial quotients will generally be better.

Program #1 isn't too bad; the multiplier (9821 in this case) seems designed to give the longest period modulo a power of 10. Again, one should choose a pair with a continued fraction expansion with small partial quotients.
