0w-20: LL14 vs. Latest dexos1: Better?

[oil_film_movies]

Trying to find the best 0w-20, and wondered if LL14 is a tougher spec than the latest dexos1-2015 spec we're seeing now.
BMW Pennzoil-sourced 0w-20, or Idemitsu gold bottle dexos1 0w-20 just coming out meeting the new 2015 dexos1 spec. ???

From the numbers I would say Castrol Edge 0W20 due to the TBN of 11.63 unless thats a typo?

While good, TBN isn't the big picture.

The latest dexos1 iteration is out in a month or two, although the hard to find Idemitsu already has it.
Wondering if LL14 is already specing better wear, deposits, etc, than the new dexos1 spec.???

dexos1 does have great new LSPI requirements which I don't know who else has though, at least until a couple of years when GF-6 is finally out.

Maybe we'll see an oil rated both LL14 and dexos1:2015, that would settle it for me.
