List of important factors to be considered before engaging an IFA

So now I have 2 good friends who are both IFA, and I'm thinking of engaging one of them to be my FA to help me with managing my finances. And we know, for IFAs, they have the data and information of policies and plans from the different insurance companies in which they can help you to do comparison before advising you on what to procure and what not to procure etc. In this case, then what are some of the important factors that I should compare and consider before finalising my decision on which one of the two to be my FA?

​

Cos if it is those normal tied FAs, I can just compare what kind of plans/policies that their company have, what is the amount of the premiums for each of those respective plans/policies, and what are the kind of benefits that the plans/policies have in store for me if I were to purchase them. But however, such kind of information and data are already readily available for IFAs. So what else can I compare and consider?
