I'll leave it to you to discover which of those two charcteristics you find you like less. Perhaps you'll just have to experience the other to figure it out for yourself.
But perhaps I don't entirely understand your problem in India. Does it really matter that much if they change whatever flights you fly on a given day? What matters to me is whether the airplane is safe, the money is on time and the leave days add up to what I'm entitled to. Most of the rest, particularly what flights I do on what day when I'm away from home don't really matter that much at all, at least not to me.
Anyway, if rosters that don't change are your priority, you will enjoy Korea. Just remember that when you spend your 21st day looking at a Korean "snack pack", have the infamous "red dot" on your forehead and are looking at a 10% outside of contract "haircut" to help fund your Korean colleagues' new sets of outstation golf clubs, all conveniently located at stations that you on the NG will never see.
Have fun,
