Meyers Briggs and Keirsey are very similar, but there are some differences. Overly simplified explanation: MBTI primarily tells you what your work persona is like, whereas Keirsey is more comprehensive.
On MBTI I test as an ENTJ; with Keirsey, I'm ENFP - 100% across the board in all four categories. It is true I have a very different work persona compared to outside of work.
ENFP's are Idealist-Champions. So if you see me raving about a product, that is very typical of a champion. We get passionate about things and want to spread the word and share with the world.
My DH is an ESFP/Artisan. This is the type that gravitates towards acting profession. He does like to take center stage and he has a dramatic streak. We are well-matched in a lot of ways, but the difference between the N and the S makes it interesting. He's more sensory and externally focused on his surroundings, whereas my N makes me more introspective. (Not the same as introverted).
The way I like to describe the difference is to tell this story: we will be driving in the car and I'll be obsessing about some work issue or whatever. Doing what I call my "navel-gazing." My thoughts will be preoccupied with the future and the "what if's"? I will be sharing with my DH because I'm extroverted so I am talkative.
He'll interrupt me to say - "Wow! Look at that sunset!" or "Wow - that's an incredible example of such-and-such architecture" (he's very into architecture). Or "wow - did you see that guy with the purple mohawk?"
When we first started dating, I'd get upset with him over this. I thought he wasn't listening to me. Then I realized that is just how he is - he truly lives in the moment, and nothing escapes his notice. He's constantly plugged into the sensory experience around him. And when I realized this, I came to really appreciate it - because I no longer miss the sunsets or interesting buildings or purple mohawks!
Likewise, I balance him out because I have a way of helping him be introspective when he needs to be.
