I think there is a question in the mishna berurah if davening biyechidus in the beis hamedrash that you learn in is preferable to davening with a minyan in a shul
there seem to be two factors regarding davening with a minyan, one is that with a minyan you have the zechus of the tzibbur, the mephorshim explain this does not just mean that you have the merits of the tzibbur but also it means that the tzibbur is always misdabek beratzon Hashem whereas an individual might not be so if you make yourself part of the tzibbur then you are automatically misdabek beratzon Hashem. The other factor seems to be something along the lines of the ramban at the end of parshas Bo who says that the tachlis habriyah is that we should stand in a minyan and be modeh to Hashem be’rabim that beriyoseachah anachnu.
