First, welcome to FlyerTalk!

You'll probably find as many votes for the one as for the other. Its very much a question of personal choice.

For me, I find 1A and 1K slightly claustrophic and noisy because of people using the wardrobe. I prefer 2A and 2K, choosing A or K depending on whether the sun will/won't be a problem.

When travelling together, my wife and I prefer 2A and 3A, or 2K and 3K. This means that we are one behind the other with a great view. We share meals using the buddy table.

Others may have different views. One thing. All the seats are good.
