Personally I believe referring to yourself as one of them can be misleading. As was mentioned, personality fluctuates a bit, so I like to tell people to do it three or four times, switching answers that give you pause.
I'm an INFP at my core, but INFJ also matches me very well, as well as INTP and INTJ at different times. If you're less than 30% thinking over perceiving, for example, and you got ENTP, check out ENFP too. It's best to use two for most people, IMO.
