If God is God, he is not good. No good God would want suffering. Any all-powerful God who allows suffering is not a good guy. Suffering never produces good. The best world would be one without any suffering of any kind.
All religions say basically the same things, especially in ethics, which is what is most crucial.
What matters most is intensity or sincerity of faith, not its object. Fundamentally, religions differ on what it takes to approach God. A works approach is common in religions, but Christianity teaches faith apart from any works. Most people are basically good and deserve the reward of heaven. We tend to think to highly of our own capacity for good and much to casually of the insult to God's glory that rejection of him actually is.
