Religion or Spirituality?

Do you think it's more beneficial to your health to be spiritual, or religious? Which do you think is MORE beneficial in your daily life and well-being?
I believe that spirituality connects you more to yourself, and self-knowledge, whereas religion connects you with other like-minded individuals, and a common connection.
As to which is more beneficial, I think it's all about what you're hoping to achieve, but I like to think it's better to have knowledge about yourself, and your inner-working.
