You forgot ANTLR.

I'll only comment on byacc/j, since that is what I use. It is Berkeley
YACC, but it generates Java instead of C. I don't know what else to say
other than it is YACC, the parser skeleton is well-written, and it
works. If you are already using and happy with some variant of YACC,
going with yacc/j is a no-brainer.

Support is rather spotty, although a new version was released last month
fixing a few issues. There really isn't much development going on with
any YACC, so byacc/j is no different in this regard.
