Usually, IAS is the more preferred cadre. Rarely, candidates prefer IFS over IAS but it does happen.
IAS gives you greater opportunity to have an impact on the lives of citizens of the country and definitely provides you with more power.
IFS, while giving you an opportunity to travel, is more like a PR person. You need to attend diplomatic functions, attend to ministers and officials visiting the country and send updates apart from the consular tasks. The power to influence the citizen's life is much limited as compared to an IAS officer. However, it is good if you are posted in an important country or posted in MEA.
