M1 ESP has been highly recommended. All things being equal, what’s the difference between M1 ESP and M1 ESP X2?

Well, not much equal between them. They carry different approvals. The X2 targets fuel economy, but it is still a stout oil.
I would go ESP 0W-30 in a Pentastar.

How about the SHELL T6 Multi-Vehicle ( now M-V ) 5w-30 ?

The X2 is simply the name they use for their 0w20 version of ESP while the other ESP oils without the X2 moniker are the 0w30 and 5w30 versions.
