I almost always use SQ, economy for short haul and business for long haul. The service and professionalism of the crews is always impressive, despite some of the garbage behaviour displayed by some pax, particularly up the pointy end.
I have used EK, KLM, BA, CX, TG, MAS and GIA - GIA used to be bit of a joke in my Jakarta days but now it is pretty decent. KLM & BA I am sorry to say just were not as good on service or seat etc.
To the point about Asians being timid and subservient, that poster may not ever have been in a hawker centre in Singapore, or HK...
