I like Maitri and I like Naranjo. Haven't read too much from others tbh.
Not necessarily sold on the spiritual stuff but Maitri's descriptions of the types seem the most real and understandable, and Naranjo also describes types in a way that makes sense...
Beatrice Chestnut tends to irritate me but I'm not sure why. Riso Hudson falls flat for me.
I should read more, for sure.
edit: Oh, I like how specific Tom Condon can be. But I'm never sure if I agree with everything he says.
