Well, I made some arguments and encouragements for research on the trinity above. Not so eloquent but I hope you do look into it some more.
From what I've seen, witnesses are the only religion that never frankly apologizes for its mistakes. I read a lot about religion, and they all apologize. Even the Catholic Church apologizes. For JW's to call Christendom pompous really takes the cake.
No, none of them are perfect, but most are less flawed than the witnesses, seriously, and a lot less self aggrandizing. You're going to do what you want to do. It would be good tho to keep an open mind on this as you go through the next few years. Keep your eyes open. Talk to people in other churches.
