The latter can recover files by finding their headers and trailers within the raw data... but it's quite finicky and awkward to use (and it doesn't seem to recover filenames very easily, if at all). The former contains over 20 utilities for reading/manipulating files/data. As with Simon's advice, if you can make an image of the disc and work with that - it should be a bit quicker than using the raw disc itself!
