There is no meditation that works for everybody; one has to find the right technique for oneself.
Let your experience and insight decide which one is good for you, as per your liking, inclination, temperament and objective. It will likely be whichever technique you feel naturally attracted to and feel most comfortable doing.
You may also take up something suggested to you by your teacher. Sincerely and regularly practice that technique—do not give up. With time, you will start understanding the subtle aspects of that particular technique.
If you are confused about which meditation style is best for you, you may try each one for a short time, and choose to stick with whichever you feel the most connected to.
