I’d suggest haul haul in the Middle East is a lifestyle option so it depends where you want to be in say 10-20 years? Long haul isn’t for everybody and I suspect that if you’re working a for a ME operator you’ll work hard. Have you any contacts out there already who can advise you. Personally I think lifestyle and the company you work for are more important than a command but each to their own. One piece of advice I was given by a trainer who had worked out there went like this. “The life style may seem great but after a while you’ll want to come home. Now you’re middle aged and you’ll be lucky to get a direct entry command so you will be back as a junior FO on a huge pay cut”.
That was enough to put me off ever applying!
