What a sad little bunch we are.
The OP asked a polite question and has had to suffer abuse and see his (her?) thread hyjacked by self-serving ego maniacs who have more to say about their own sad existence than, to be honest, most of us really need to know.
Matmax (and others) if you want a willy waving competition join a naturist society.
To the original OP.. It is more to do with historical precedence and the common English language than the perceived difference in quality of one license to another.
As has been said already, Asian MROs 'like' the UK CAA license because they are familiar and comforable with it.
Good Luck in your endeavours and ignore the abuse.
