From experience in my group Oleander feels a bit like it invalidates the basic Death Head in most cases.

Who cares you can only shoot 1/round when you can OC loop reload anti-mat rifle without ordnance and ignoring enemy resistances. Stack on Roland chamber, op cal and crack shot and you're essentially able to one shot every standard enemy and even some multiple structure ones.
Being able to heal yourself once per scene, gain seeking and crit on 18 is just icing on the cake.
