Morticia vs Mortarion?

New to DG and Warhammer as well. What do you all feel about using this model with Mortarion’s abilities as if it were him. I’ve found the one called Morticia the morbid queen model 3d print and like it a bit more than Mortarion. I know you can’t really use it in a GW event so I may end up with both…. Just looking for what you all think?
