I'd much prefer to deal with Pu than ClF3. Reasonable care will keep you safe around the Pu, any little flaw that you have no idea exists can unleash the ClF3 demon. But why stop at ClF3? FOOF seems an awful lot more dangerous, you can at least cage the ClF3 demon, nobody's crazy enough to even try with FOOF. FOOF will detonate if it gets too warm (and that's at cryogenic temperature.) It will detonate if it's disturbed. It will detonate if you look at it (photosensitive, not the actual looking.) It might detonate for no reason at all.
