Is the reward for praying in an open area equipped with tents, loudspeakers, and carpets for the purpose of prayer the same as the reward for praying in a mosque, or does the mosque have superiority?

If the prayer areas and temporary prayer rooms are not endowed for permanent prayer, then praying in mosques is better, because the prayer room does not fall under the rulings of a mosque. However, if they are endowed for prayer, they take the ruling of a mosque, and praying in them is like praying in the mosques of the neighborhood or city. The best is to pray in the mosque with the largest congregation.
