Personally I can’t stand 3rd person omniscient. It takes away all the suspense and character development If the reader knows what’s going on in each characters head. I find fanfic writers abuse it a lot and it’s a massive nope for I basically stop reading. But I understand it’s appeal lol it’s very popular in smut scenes and I understand why.

thats kind of my beef with it too, but more so from a writer than reader perspective. i don’t mind reading fics with it as much but if i’m writing i usually do a limited perspective kind of for the reasons you said. like a lot of my stories rely on one character not knowing or understanding the other character’s thoughts or feelings, so omniscient would be weird for that in my opinion

I guess it makes more sense in smut when you want to describe both characters feelings, but even then its not my usual go-to perspectiveÂ
