I'm not sure what version you tested, but I do know they made some changes
that have really improved the time issue. Whether or not it's still that
much slower than WWP I don't know. Also, from my limited knowledge of WWP, I
think it doesn't have the output flexibility of RH 4 FM. In other words, I
could output the same project to two .chms and have different conditional
text show in each one (along with other options). Or I could output the same
help to .chm and also to webhelp. Remember, I can set this all up and so I
can get these output without making any changes to the project, just compile
the output and off I go. I don't think WWP does this. I could be wrong. With
that said, I agree that the products are very similar and a decision between
the two products is largely subjective.
