I think that more formal brand of logic comes out in INTP because they're explicitly concerned with models. They might idealize their decision making approach from an underlying blueprint of Logic. And maybe outright point to it in a "Spock" like manner, saying something "Logic dictates that..." I think it even comes out when they try to be worldly - like look at a lot of the "PUA" literature. I bet most of it is Ti/Ne - the approach is very mechanical and rules based, rather than casual. It's not really fluid and in the moment decision making, but If/Then/But scenarios.. little logic games to spark interest in others. Se is going to be implicit in it's logic, practical, specific, even casual sounding to the point of being mundane, pointing the logical flaws through specific scenarios and objects. The model is in the unconscious, if there is one at all. But even all this is an exaggeration probably. I'm sure if there were two ITP kids or something, they're going to look fairly identical most of the time. Especially when it comes to Inferior Fe. At least I don't buy into the idea of being cooler than INTPs. My social skills have always been a source of problems. Se isn't the only thing needed to be "comfortable" in your skin - all E - extroverted - functions are needed to be awesome in the world. That's the nature of extroversion - it deals with the outside. I'm guessing Fe more than anything, since "other people" are a big equation to the outside world.
edit: Speaking of which, I'm writing this nonsense on New Year's Eve, alone, watching the Walking Dead. Story of my life. Shows how cool I am.
