Delta Economy+ vs Virgin Prem Econ-Intn'l?

Soon to fly Atlanta to London and can probably choose between the two. Anyone who can compare and contrast? TIA

Totally useless for you, I suppose, but Virgin Atlantic Upper Class was a far better experience than British First.

Virgin by a landslide even though Delta owns half of VA. I find service much, much better on INT carriers that fly over the Atlantic.

over the atlantic
over the pacific
over land
over the poles
over the moon

Virgin by a country mileā€¦

For sure
