All religions have great teachings, morals and stories. One can read all of them and find some truths in each. They are all meant to make you a better person. It is when greed gets involved and when people question which is the best that any religion can become the opposite of what it is supposed to be. These days people blindly follow businessmen (no longer spiritual guides) to perform different rituals and ceremonies and have their money taken from them.
If you follow the correct teachings and accept all religions, then you are on the true righteous path. If you are a spiritual person then by all means do the rituals and ceremonies but do not blindly follow and be exploited.
I'd say every religion has great messages to learn from, it is the portions that discourage people and put them down that should be renounced.
If god/gods are all loving and good, they would not want to see suffering. It is the minds of man that twists religion and makes it a tool for the easily influenced.
