Here I am giving you certain points which can assist one to decide on his own which is the correct vocation between IAS and IFS.

IAS offers more power along with perks and benefits but the cadre allocation policy is very random. IFS offer to visit most important countries during an ones lifetime.

IAS gives one greater opportunity to have an impact on the lives of citizens of the country and definitely provides you with more power.
IFS, while giving one an opportunity to travel, is merely like a PR person. One needs to attend diplomatic functions, attend to ministers and officials visiting the country as well as send updates apart from the consular tasks

IAS is an All India Service while IFS is a central service.

In IAS u will spend around 75% career in the cadre state which was allocated while in IFS one will serve two- third life in foreign designation.

If one want power or authority then IAS would be the obvious choice and If one want a exciting life and has an ability to represent India in international forum, this service is desirable.

An entry level IAS spend his career in remote village or teshil whereas an entry level IFS officer has a choice in which country he/she wants to work for.

Legally an IFS officer earns plentiful money as compared to his IAS counterpart
and there is less political pressure in the work. After being an IFS officer one can be deputed to International organisation such as UN and its branch dept., WHO, etc.

I hope this might have cleared the confusion you had about the choice t be made between IAS and IFS.
