HI, I have used VP++ for some time but finally switched to ANTLR.
Biggest problems are you can't include code into your grammar file
(there is a way but it's undocumented and has some problems). It
doesn't support the specification of grammars in such a nice way as
ANTLR does. It's a DFA based parser whereas ANTLR produces a top-down
parser (at least I think that's what it does ;-)). This means the
generated code of ANLTR is quite debug-able, with the VP++ stuff you
can only debug your code not the parser internals.

For me ANLTR is the best tool at all for parser stuff! It's easy,
fast, high quality and supports really advanced features missing in
every other tool.
