What do you find “great” about Reformed faith?
Like Catholicism, Reformed Christianity is a world view, not a navel view. It nourishes the mind, rather than attempting to supplant it. It gives place and glory to God, rather than attempting to ramp up one's own experiences to the point where they can take the place of God. Finally, Reformed Christianity has a track record of creating godly and prosperous commonwealths, with a high degree of both liberty and order.
Thanks for asking, and may the God of all truth continue to enlighten our pilgrimages.
