I also think it matters more in how a person "feels" about the "faith" they are leaving.
If one were raised in a Christian family, and religion was more or less forced on them, also if they didn't agree with the beliefs finding something they feel is right for them is important.

Everyday problems teach us to have a realistic attitude.
They teach us that life is what life is; flawed.
Yet with tremendous potential for joy and fulfillment.

If your path teaches you to act and exert yourself correctly and leads to spiritual realizations such as love, compassion and wisdom then obviously it's worthwhile.
~Lama Thubten Yeshe~
One whose mind is freed does not argue with anyone, he does not dispute with anyone. He makes use of the conventional terms of the world without clinging to them
