Thanks ung1 for doing this, great idea.
As a FF for BA where I never used the Economy plus, I would love that Emirates would introduce this or use this on the old Biz seats on some aircrafts.
I also like the upgrades or awards using miles on BA, EK's upgrades or awarrds with miles are too high where BA is very low compared to EK.
Arrivals lounge will also help sometimes.
Though I would also say that EK has some advantages, I would take EK's Biz over BA's First anytime.
