PDADS seems to crash a lot for me. I tried out DSOrganize and thought it was a little bit nicer.
I guess give each a shot and see what you like best. I don't think you can start DSOrganize from the main PDA menu though... not sure if it can be customized to start DSOrganize instead.
Any time it looks like you're in an unwinnable situation that will require you to restart the entire game, it overwrites all your saves with that autosave.
