With Family Tree v 2.0, the descendant box chart looks nicer than the one that UFT 2.9 generates and that's the main reason that I use this particular package. It's also the one that my father uses, so I'm trying to make sure that everything that I enter into UFT translates across ok to the other package.
As for PAF, I like the way it generates an indented descendant list. It seems to contain more data alongside each individual. Something that UFT seems to lack with the version that I've got.
