It's hard to tell the difference between PAO and Group III oils in UOA, but ester oils are easy to spot. The Nissan oil is not substantially ester based. Compare some UOA results on the Nissan oil to Redline or Motul 300V, you'll be able to tell too.
The short answer is Eneos is not worth it. No boutique or import oils are. When you can buy Mobil 1 for $5/qt and Pennzoil Ultra for $5.75/qt at Walmart, nothing costing $9+/qt is worth it unless your car requires some uncommon OEM spec oil like say, VW 504/507.
