IceToolz E272 ... is meant for removing paint while the Park Tools one is a proper facing tool (i.e. it can clean up carbon fiber).
If it could remove paint in the way it's supposed to (by cutting, not by mauling through with excessive pressure), it would fair well at carbon, too. If the pictures are anything to go by, that is a big IF, though.
Apart from that, agreed, it's not all that useful without the alignment bits and bobs.
