Yes, MDCrack should be faster (in terms of hashes computed per second
when used against a single MD5 hash) than the contributed JtR patch for
raw MD5 hashes.  However, MDCrack is likely to be less effective in
practice if used on its own because it is much dumber than JtR in the
way it generates candidate passwords to try.

One possibility is to pipe the output of "john ... --stdout" into
MDCrack.  One downside of that approach is that if you interrupt and
continue such a JtR + MDCrack run, some buffered candidate passwords
(a few hundred is typical) will be skipped.

Oh, and the URL for MDCrack is:
