BTC stretching vs simple manual stretching

Hoping that I could get some feedback from some more experienced PE’rs. I am deciding on which type of stretching to do. Based on my observation the BTC stretch seems to be the simpler approach but the simple manual stretch seems to be more thorough. I would appreciate hearing from guys who have attempted both as well as proponents of both methods to help me decide which approach to use.

BTC only stretches one direction. It woul be best to do both that way you stretch in all directions.
