This is closest to my experience with ILI and SLI.
One thing I noticed in my friends/family is that the SLI has more traditional moral values even if they can seem a bit warped and unfair to me. For instance, his beliefs almost border on the misogynistic sometimes if taken at face value (not saying they are all like that). He wants a traditional wife and family even though his lifestyle is not really traditional since he is a tattoo artist. It is like he has two distinct personas. One where he is the fun-loving,, cool guy who has groupies and the other is the the traditional family man who moralizes about everyone else's behaviour but his own.
The ILI I knew were way more in their heads and didn't seem to be hindered by traditional morality since they used more logic when examining moral issues. They were also very careful with their hygiene.
By my standards, they had deeper philosophical thoughts, and could sway me to believe in many things, that others couldn't, just by purely rational/logical explanations. It was often hard to find a good counter-argument during debates with them because it is like they had it all figured out. If I did't know the topic well I was way out of my league. I think they influenced me to be more analytical.
It was easier to debate the SLI on moral issues than it was to debate the ILI on any issues. I never felt out of my intelligence league with the SLI who I am closest to but he was not very well read or anything because he was into one on one sports (mainly while he was in school) and sort of built an ego around his strength and vitality. This is an attitude he still carries even though he can no longer participate in his sport. If he hadn't been hurt I am sure the SLI could have made an great MMA fighter. He is an excellent skin artist though.
Both the ILI I was very close to had that robotic sort of feel to them but once I got through that exterior wall I felt I had way more in common with them than the SLI. I certainly had more to talk about with them than the SLI whose interests are very different than my own so we had trouble connecting on that level.
