Eh brah! My collection of over 100 pieces are mostly Asian 21J movements. Some are over 7 years old and none of them have given me any troubles. I guess I prefer the asian ones right now due to price and reliability. I am not that much into 1 to 1 reps vs gens as others here are. It all depends on what you are looking for and how much you want to spend.

Mahalo nui loa!
