I prefer the anime versions.
When I was in my teens, somehow I thought manga UraNep were superior and better people, but...no.
Uranus forces a mouth kiss on Usagi just to mess with her. Then proceeds to stalk her and get in her head.
Both attack the inners for no reason during the Mimette fight.
Don't get me wrong, this was kind of interesting during those chapters because...oh my...are they allies? Enemies?
But then, in typical manga fashion, it amounts to NOTHING. Same as the Uranus is a Tuxedo Mask panel.
After these first couple of chapters full of intrigue, UraNep just become simping toadies who scream "Purincessu" every few panels. Same as the rest.
Anime UraNep do make some questionable and stupid moves, but we get to see their conversations, the motives make somewhat more sense and while yes, they can be very rude and antagonistic, they seem like actual characters. By the end of infinity they don't really stand out, whereas in the anime, they are still their own thing. Even into Stars.
Speaking of Stars, the first part of the manga makes them more relatable but then...oh well. Back to the usual. Not enough chapters for so many characters.
The manga characters only seem less 2-dimensional because we fill in the blanks with our imagination. It's okay to enjoy that, I did as a kid...but it by no means makes them written better.
Plus, as a side note, anime UraNep get this:
Crystal UraNep get whatever this is:
It's pretty... but the most generic piece of music in Crystal. It definitely doesn't suit them or that scene. It's no wonder every video you find of that scene has the music replaced with the 90s theme. What were they thinking?
