Conde Nast Traveller (UK) or (US)?

Hey everyone,
I am in a dillemna, I cannot make up my mind in deciding which magazine to choose. I would like to subscribe for Conde Nast Traveller, but for which one should I go?

(UK edition) or (US edition)?

1.Which one offers the most comprehensive outlook on more destinations over there world?

2.Do Conde Nast Traveller Magazines contain enough information about Airline industry?

Thanking you,
Gohar:)
