Are there in better 0W-20s readily available on the market when it comes to wear protection while still meeting Dexos 1?
That is a nice enough vehicle that I'd just get the best. Similar to OVERKILL's recommendation, but go with Mobil1 Annual Protection 0w20 instead of their "extended protection" older product.
That is Mobil's best and latest attempt at tech advancement in additive chemistry and base oil composition. Costs a little more. Worth it in nice vehicles under stress.
Both show as having the same range of PAO in them (60-70%), so I'd wager they aren't really much different from each other. If he's not running super extended drains and can get EP cheaper, I can't see AP being enough of a step-up to warrant spending more.
Now of course if they are both the same price, AP is the obvious choice.
