Having experienced two out of the options listed, I can only compare between them, so cannot advise. But EZ LGW and EK A380 are really comparing apples and oranges. This decision has to be based on where you need to be based and where you see yourself in five years time.
I enjoyed my steak and 6hrs sleep on the way back from Australia... and it was a lot less work than four sectors through LGW any day of the week. But if you prefer to end the day in a traditional pub garden (prior to collapsing in bed for 7hrs ready for the next 11hr epic in-and-out of the South East) rather than pool and sand then that's a personal choice.
Also, your lifestyle requirements will change in the next years. What offers more flexibility for your particular needs? It's a never-ending discussion. Do your due diligence, look at rosters, visit the places, check out the house prices, make a choice and get on with it.
