Parrot seems to have a ton of language implementations build using it, but very few are complete implementations (with the exception of Perl); they are just tests of Parrot as a compiler infrastructure. The DLR has two fairly-complete language implementations (IronRuby and IronPython), along with some other test languages, that may or may not be available against the latest source code (JavaScript and Visual Basic existed against an older version, Scheme and Lisp are among the available ones today).</span></p>

The DLR provides a way to get from a syntax tree to CLI code; it does not provide (or lock you into using) a specific parser to map your language to DLR syntax trees, and it uses any CLI-compatible VM to run on (CLR or Mono). The DLR also provides mechanisms to cache dynamic method calls, and make your language interoperate with existing CLI code.</span></p>

The comparison you ask for is not even apples and oranges, More like mushrooms and turnips :)<br>
