all fun lasted till the day u happen to settle down in sg. nobody can predict this

that defeat the entire purpose of sacrificing KL life to work for years and save money

Choose the one with career path/usefulness of job role for FUTURE. Don't fall for sgd trap. If you're not with local degree, chances are employers hiring msian is leveraging on cheaper labor cost. Also, its easier to rise up the ranks in msia as generally ppl are 3rd world and not as bright, sg u gotta compete with tons of foreigners whose also hungry for sgd while being berated with local work culture.
And once u stayed too long, its harder for u to return as u will not consider a lower pay MYR despite good opportunities. However its no harm to consider sg experience a stepping stone for entry to good mncs worldwide in future
