I've taken the MBTI test multiple times and my type keeps switching between INFJ and ISFJ. Is there a main difference between the two functions Ni and Si that might help me determine which is more suitable for me?

I also got both. [Even on the 16personalities.com test. In my case, I was almost exactly 50/50!]

I would suggest picking the one you feel suits you the most or stick with both of them (like me).

Honestly, I don't think there is a huge difference between the two.

You may have very close sensing and intuiting preferences, able to use which ever is needed in any given situation. Keep in mind that personality type isn't some static thing that anyone is is trapped in. We all have access to all the cognitive abilities, and the ones that are strongest are the ones we've preferred to use, and thus have practice using. We can change our preferences anytime, and begin to develop whatever cognitive functions we want (to varying degrees of difficulty, depending on the person). It's entirely possible for you to have preferences for Si and Ni in equal or close to equal measures..

Ask yourself if you're more interested in pondering the possibilities of the future (Ni), or being grounded in the lessons of the past (Si). Or, perhaps you prefer both in equal measures.
