The nice thing about fusion neutrons is you get to control the isotopes, you have no control over fission waste isotopes.
Some fission isotopes are really icky to deal with, as everyone has heard...
On the other hand if you don't like dealing with cobalt-60 waste at your fusion plant, simply stop using cobalt alloys in your reactor vessel.
It turns out to be "not that big of a deal" to design a fusion plant where neutron activation isn't important. The quotes are because nothing is easy in fusion but as a problem its pretty low on the list.
