Before this, I chose to use Gengar's Japanese name for the sake of consistency, and the fact that his name is similar to his English name helps to.
Anyway, the newest Ghost is also a final stage like Gengar, as he/she has two previous stages of evolutions to go through first. Not only that, this Ghost has a HUGE Special Attack, reaching a Base Special Attack of 145!! Although its Speed is only Base 80. Compared to Gangar, who has a Base Special Attack of 130, but Base 110 Speed.
I think I would have a hard time choosing between the two without making sacrifices, but I would welcome our new Ghost and choose Shanderaa. But I think I will cheat and choose both.
