Eaton vs. 14 Bolt vs. Dana 60

[Chevy1TonFun]

I have an Eaton rear end with RJ H02002 stamped on the third member. What ever that means I not sure. I don't know much about Eaton. Since buying and building this truck I asked all the offroad shops and nobody knew what it was and had never seen it before. It wasn't until I showed Jeff at ECE that I found out what it was. He also told me that they are hard to find parts for and to get rid of it.
But lately I've been told that an Eaton is strong rear end and to keep it. I would like to get a different rear end with gears and a locker. I'm looking at a 3/4 Dana 60 or 3/4 14 Bolt. What should I do.... I need some input.
