Performance and a time saver. If I'm not using one kind of fast setting epoxy, then I choose to use E-flite Medium CA with the Activator. Regular super glue takes a while to set up and dry. CA with the kicker will set up in seconds, bonds better and depending on the formula, flows slower.

And when you sand both mating surfaces (and on larger parts, drill holes) the bond is as good as epoxy. Just don't overdo the kicker.
