I find the Fe subtype of SEI most annoying of all. The ones I know pretty much break everything they touch, place objects in places from where they will surely fall down etc. and then make a big drama out of everything. It can be fun for a while, but in the long term I start feeling like I'm babysitting someone who will never learn anything. And it's sometimes hard not to think they fuck things up intentionally. Esp. Fe-SEIs also tend not to have much to contribute to conversations that go beyond what's for dinner, which is apt to strengthen the airhead impression.. I don't know why this is all so annoying to me, maybe it's just the benefit relationship. IEIs don't piss me off half as much and I'm usually not afraid to let them handle my stuff at all. With SEIs I feel like I have to provide a lot but never get anything back.
This is not to say I hate all SEIs or anything (I could write a similar rant about pretty much any type plus individuals are of course different), but in general I find SEIs more annoying than LSEs.
Yeah I know a few LSEs like this, too, and feel the same way as you do. I see this happening usually with E8s and/or Te subtypes only, though.
Si subtypes (or harmonisers/creatives) and 6s and 9s are usually super cool and laid back ime.
