Probably to early to judge, since obviously not everything is implemented yet:
What good is the [BIO] function of the lab? What do you need Zombie juice for? Will you be able to look for her other experiments with further research?
As far as I can see, the benefits are:
Hire: +250p; 4/9 unique Research; Ocular, Lab OR Car
Prank: -500p; 9/9 unique Research; Car, Lab (also follows from one of her unique research, but with a score penalty)
Humiliate/Enslave: +1000p; 4/9 unique Research; Ocular, Car, Slave (which you can milk for an infinite amount of Zombie juice)
Humiliate/Abuse: +1000p; 6/9 unique Research; Ocular, Car, Vampire (combat unit)
Banish: +2500p; 0/9 unique Research; Ocular, Car
Merchandise: +1000p; 5/9 unique Research; Ocular, Car, 2M$, 2000 Jacks Bounty
Banish right now is a waste.
Merchandise gives you a quick boost in tokens, but you get nothing unique.
Hire seems inferior to Prank, since you just get the ocular for far less research.
The vampire is not a bad combat unit, but is less useful late game.
The usefulness of the slave depends on the future usefulness of the zombie juice.
I went with prank.
