I personally think flight dispatcher is a wonderful. There is alot of responsibility for this role and alot of opportunities especially in the middle East [Emirates in particular]. If you loot at their careers website you should be able to find alot of dispatcher vacancies advertised.
I used to work for Emirates about five years ago but my recollection of the take home package would not be very helpful but bearing in mind the responsibility and scarcity of personnel, I would think the pay is good.
I would suggest you visit the careers websites of these Airlines and perhaps research further into the role before you could make up your mind.
Best of luck.
