OK, that walk through video makes it look better and larger. But we should know it is larger as it is 1-1-1. With AF's 1-2-1 private suites the two window suites are smaller in width but of course it has the advantage of allowing a couple to have a private suite in the two middle seats.
I won't judge which is best because I would be VERY happy to be in either the EK or AF suite. But again, it's EK catching up to AF with the private suite and still failing to match AF's industry best ground service.
