Meditating with Discover Meditation (mantra) EnlightenQ and LifeFlow for almost 8 years has been life changing for me in so many ways. Because your question is about some types of meditation that I have not tried, I hope the following two pieces may be of great help to you, written by Ta-tsu-wa who is highly revered in the community
"Each of us is unique, and what works well for me might be totally useless to you. Generically speaking, there are three types of meditation techniques. There are techniques that take your awareness outwards, techniques that take your awareness inwards, and techniques that do a little of both. People with exceptionally busy minds tend to do better with techniques that take awareness outwards since their minds naturally head that direction anyway. People with more contemplative natures tend to do better with techniques that take you inwards. The combination techniques are a “maybe” for just about anyone, but are usually best used when a person has some experience with meditation under their belt.
The mantra technique as taught by Michael at Project Meditation is an excellent example of an outward technique. Since the vast majority of people have somewhat active minds, this mantra technique is a good bet for most of us."
"The "preliminary exercise" in EnlightenQ is in fact a sophisticated meditation technique in its own right. I can see the roots of the Q Exercise in several very advanced meditation traditions, in particular, Surat Shabda yoga and Taoism. The Q Exercise employs the same principles in a very unique way with actual audible sound as the focal point. The mechanism used in the Q Exercise is one of the most effective I've run across, and with some dedicated effort I think just about anyone will succeed if they're willing to put in the time to practice."
