depending on what you are looking for
rally championship: "true to life physics"IMO, nice graphics, demanding with
very long stages in all kinds of conditions, nice variaty of cars, all with
different handling. really nice sounds
rally masters: a bit arcady feeling, smooth graphics, not so good stages,
average sound, race head to head is a good feature thou
Conclusion: rally masters is the better game!

You could probably find arguments all over the place as to which one has
better phyisics but they are both pretty equal in that repect...each one
excelling in some areas and coming up short in others. RC has better
graphics but is more of a system hog becuase of this. RM is a faster graphic
engine but the stages are sometimes blan. RC has better cars and a much
nicer damage model.
However, if you are looking for head to head racing then you should go with
Rally Masters which offers by far the best arcade mode of the two. Rally
Championship is more indepth and harder to complete, geared more toward the
sim market.
Just my 2 cents
