If you haven't read the Jersey thread, there is now an interesting extra quirk to this discussion.

If you enter Jersey and test positive, you are placed under house arrest for 14 days. More importantly, everyone sitting in the 2 rows behind and in front of you is also placed under house arrest for 14 days. You will be in a property provided by the Government, not your booked hotel.

On this basis, Row 1 or the very back row is now substantially the best choice, because it reduces by 50% your chance of being caught up in something like this if another passenger tests positive.
