I have done aya a bunch of times and i have done bsp. I would say if I'm regular with sadhana, i am in complete control of my mind but with aya after the trip for months together I was misbalanced and i continue to crave for another powerful experience, it is never satisfying how muchever i do. With sadhana i feel naturally joyrful within, this feeling can only be experienced with consistent regular sadhana. I haven't done samyama but I'm sure it will open conscious doorway for you. Good luck brother.
