In my experience of about a dozen years, the Daoist path has stuck with me as a method to transform/cultivate/raise the energy in the body. I find Daoism to be a more powerful path because it presents a very clear, scientific map of the inner landscape of the body. A map in which you are the scientist and the experiment and you observe the Placebo effect.
In short, kundalini meditations and yoga (which I semi-regularly for about a decade) feel like shooting fire up my spine. It's powerful, although it feels undirected. I don't have any experience with TM, although I did a ten-day silent meditation retreat which was very powerful. However, it's difficult to cultivate the kind of energy at a vipassana retreat in a daily practice. Daoism led me to sexual cultivation, five-element theory, the three treasures, the microcosmic orbit, and the mixing of kan and li. Daoism feels like a path that builds a strong foundation for the energetic body to undergo the kind of energetic transformation that kundalini creates.
As far as the difference between kundalini and the cultivation practice of the Dao, it seems like semantics between different cultures.
