I have seen the thread on AA EXP elite level and challenge as compared to UA 1K. Is there something similar for the post merger Delta?

I'm a 1k MM with UA, out of SFO. Since much of my travel is CDG and NRT, and I now have lifetime PremEx and with *net blocking, I am thinking that new Delta with Nw's NRT route, and AF code share to CDG might be an opportunity for me.

Any thoughts, threads or details?
