I would say if you can meet both, then do so and see with which individual bird you "click" more. There really isn't any "benefit" for one over the other.
I have a few of the smaller Poicephalus, including a Senegal and two Meyer's. My Senegal is the sweetest of the three and the one I have a strongest bond with; however I did get her as a weaned baby whereas the two Meyer's came from a rescue. But to put things in perspective, my eldest Meyer's is absolutely in love with my significant other.
One thing, since you seem keen on generalizations, "cuddly" isn't necessarily a term to qualify Pois, at least not in the way most people think of when they think of "cuddly".
