it's really very simple but people make it more complicated that it is. If you are intellectually minded, you can just look at the history of the Church and see who broke away from who, and who practiced in such a way as to how the early Church Fathers described. If you do this, there are really only 3 options: roman catholics, Orthodox, and non-chalcedonians. Given the non-chalcedonians define themselves by rejecting the Church, and the roman catholics don't at all resemble how the early Christians practiced as well as leaving the church and changing their beliefs at a specific time and place in history for specific reasons a 5 minute wikipedia article viewing can teach you, the answer is clear.
or if you aren't intellectually minded, just go to Church and see the difference for yourself. I think if everyone went to 3 Roman Catholic parishes at random and 3 Orthodox parishes at random, they would not even need a history lesson or a theological argument as to who is right.
