Mainly:
  arima0 is the predecessor of arima.
  AFAIK, it has only be retained for back-compatibility but
  shouldn't really be used in "new "rojects".

In more details:
  1) carefully read their help pages
  2) read the source code :-)

?arima0

"This is a preliminary version, and will be replaced by |arima

arima0 can be faster, though, in some cases, but does'nt handle NA's
as arima does.

If you don't have a very good reason to use arima0, use arima
