Good answer.
Late here, but if you are really looking for an honest answer, there really is none. Jehovah Witnesses believe they have the better way. Lutheran’s believe they do. Evangelists believe, fundamentalists do. One follows the order of any particular church because they believe that their church has the fullness of truth also. It’s all in your own personal belief which is the better fit for you. I’ve read most of the responses here, and they pertain to the truth, the first church past down from Jesus to the apostles, the Eucharist as the true body and blood. Those answers do not make it better to be Catholic if you do not believe that this is true. Some may say that our liturgies are beautiful and the Easter Vigil is a must. That is no answer why Catholic is better. Other churches have beautiful services too.
I see that some have similar answers to mine. It is not “why is it better to be Catholic,” but rather why is it better to follow Christ and believe. In our creed, we state that we believe in on holy catholic and apostolic church. The small C is there for a purpose…meaning universal, not the Catholic Church.
If you are looking for a church, you must know their beliefs and find one that you can really believe in, e.g. if you believe that confessing to God is a personal thing between you and God alone, Catholicism is not for you. If you cannot believe that a priest can, through the action of the Holy Spirit, turn the bread and wine into the real presence of Christ himself, Catholicism is not for you.
I can go on an on, but I believe you get my point.
