Choosing advantages of one tradition over another Like all religions, there are different branches, traditions, whatever you want to call them.  Why would you choose one over the others?  Do you think one is right and the others are wrong?  Does one fit with your lifestyle?  I can see being born into one you might not have a choice.  If they are all the same thing at heart, why have the differences?  What if you choose the wrong one?
The Buddha taught all, but such an attainment is rare. Even in the Buddha's time, Ānanda asked about the difference in practice.

MN64:16.1: “Sir, if this is the path and the practice for giving up the five lower fetters, how come some mendicants here are released in heart while others are released by wisdom?”
MN64:16.2: “In that case, I say it is the diversity of their faculties.”

Buddhist practice actually consists of three practices. Different teachers may be adept at one or more of these and appeal to different students:

AN3.89:1.1: “Mendicants, these are the three trainings.  What three? The training in the higher ethics, the higher mind, and the higher wisdom.

The three practices support each other. If one cannot find a teacher for all three, one can certainly choose a teacher who teaches what one lacks.
Different traditions emphasize different practices. I first trained in Zen for mind/immersion, but later studied the suttas themselves for ethics and wisdom.
