As the title, what is the difference despite most of them offer professional advice for insurance products. For those Client Advisor, do they earn big commissions from singed up client? Thanks.

They are the same. If you really keen to buy I will recommend going to a bank instead as the product is the same but at least if the sales person leave, you know the bank will be the gurantor instead so no risk of people not "servicing" you.
