I have many contradictory thoughts on the subject in the title of this post, including:
1. Rav Moshe Feinstein wrote that who is distracted by the way his local minyan is conducted is still obligated to attend, unless he cannot even concentrate on the basic meaning of the words;
2. In the days of the gemara, many sages often davened without a minyan;
3. Rav Moshe permits missing certain mitzvos, such as sitting in a succah, for the sake of touring in special locations;
4. The Rambam (Hilchos Tefilah 8:1, and see Kesef Mishneh's sources there) writes that the prayer of the community is always heard before Gd, and so one must never miss davening with the community;
5. Certain rites - the Torah reading, kaddish, emulating of the angelic kedushah - may be performed only in a community;
6. I know Rabbis I respect who will take vacations in places without minyanim.
Much more could be said on this, but I'm curious what others will write. What do you think of this?
