The idea that any church has more to offer seems weird to me. What does that have to do with truth? Who cares if a religion offers more? Shouldn’t all you care about is whether there’s sufficient evidence to justify a belief in it? At least protestants don’t offer nearly two millennia of failure to help the poor while their religious leader lives in a solid gold palace. Not that protestants don’t have their share of con-artists taking money for personal gain, but it’s on a smaller scale.
What evidence are you referring to? Failure of individuals to live up to a religion’s doctrine doesn’t constitute evidence against that religion, unless that itself runs contrary to the tenets of said religion.
It’s also noteworthy that those whom the Church upholds as examples to follow did in fact help the poor. Sts. Martin of Tours, Francis of Assisi, Mother Teresa of Calcutta, and Nicholas all come to mind. Note that there are very few popes from the Middle Ages and Renaissance that the Church honours as saints. It isn’t as if we think they were all good popes. Many were corrupt and immoral, and some were rebuked by saints such as Catherine of Siena or Bernard of Clairvaux.
