Hard time picking my doula!

Erika
Today I interview the last of 4 doulas I've chosen to speak with. I'm leaning towards two of the four. How did you make that decision? I'm just having a very hard time deciding who will mesh well with my personality since I really liked them both. 
Both come highly recommended, but one has attended 23 births, the other 17. One is a Bradley method instructor as well, while the other is not.
