I have been meditating for forty years. For thirty nine years I did transcendental meditation (TM)as taught by Maharishi Mahesh Yogi. I sat for 20 minutes twice a day without fail.
Last year I switched to Vipassana not because I was displeased with TM but just for a change and because the Goenka community seems to be very professional. I have been sitting in this new way one hour a day for a year now. I am not as regular because Vipassana requires more arrangement than TM. I am satisfied with my practice and can see a path to grow in this community for the rest of my life.
I am not sorry that I have spent so much time meditating. It changed my life. Before I began meditating I was aware of a certain pervasive incompleteness. I am a programmer and I love programming and I have been married for forty seven years and love my wife. But these satisfactions were not enough. My meditation practice did not materially change my life but it has given me a sense of centeredness. I am in a quiet way more fulfilled.
My experience was that TM was a very practical choice. I paid $75 to be initiated and found the TM community meet my needs for companionship on my path. Community is important to support a meditative practice. The actual practice is practical to do in our busy lives. If you are too busy to take two twenty minute periods each day for your personal readjustment then you are too busy and you need to readjust your life pattern. If you do not realize the imbalance in your life, probably meditation is not for you. Don't waste your time. Perhaps later.
YMMV, nowadays it cost $2k+ to learn TM. It is a good deal at this cost at least the benefits in my life exceed almost any amount of money. But without my experience I would never understand that. It is a chicken and egg problem.
OTOH, the TM community has changed and I am not sure I would be served by the Post Mahrishi community. In my case, as a long term meditator the difficulties with the community don't really affect me. Although I did consider the quality of the Goenka to support me in future.
So the choice of TM is a possibility for a newby. One caution, I knew many poeple who started TM and did not continue. So you are risking $2k+.
Vipassana is different. The technique requires more training and a greater daily investment. I sit for an hour a day. But Goenka suggests a minimum of two hours a day. And most practioners do at least one ten day retreat a year. I find this a bit much. But given that I am retired it is easily feasable. It merely a matter of commitment for me. A midlife married programmer will find this a greater challenge.
The introduction to Goenka's technique is charming. You do a ten day retreat at no cost to you. Their story is that adopting this practice is a serious matter. You learn the technique and then practice ten hours a day for ten days. For this learning period you live on the charity of others like a Budhist monk. Since this technique is a way of living that extends beyond just sitting, you need time to get into it.
I don't know how to tell which is most appropriate for you. I can just say it works for me. But I can say one thing for certain. Meditation is a practice that must be done everyday. Don't bother if you are not ready to commit to a regular practice. The benefits of meditation can not be explained. It is an experience and all that a teacher can do is give the experience and show you how to protect it. The rest is up to you.
I will say that meditation and psychotherapy are not mutually exclusive. For more than twelve years during the last forty I have been in therapy.
My final thought is that if you have a sense that your experience of life seems not quite complete, meditation can work to give you greater experience of connection.
