Warning, this post may contain unpopular opinions, you'll see.
Just to clarify, Black Lady and Mistress 9 will not influence the rank of Chibi Usa and Saturn.
I'll start with Chibi Usa just to get her out the way, I don't like her that much, if you kept her R incarnation she'd score higher but her Super S incarnation made that season borderline unwatchable.
Mercury is invaluable to have on the team and has a personality that suits her position as strategist and her OVA gives her some extra quirks.
Venus is average at pretty much every position to the point where anyone would mistake her as an American default girl cartoon protagonist.
Sailor Moon herself is very easy to hate on and for good reason but in recent years, I'm a lot more sympathetic and the Crystal series doesn't portray her as annoying as the 90s anime does and remember I'm judging the character as portrayed in the whole franchise not just one season.
Mars is a good foil for Usagi but at times she can be a bit 90s anime girl and I wouldn't be able to separate her next to similar looking anime characters.
Jupiter is probably the most complete female character in the anime medium, she's fiercely independent but has grace and femininity often surprising herself with what she's capable of.
Saturn is a bit of an enigma, while she has a back story that can put many tragic characters to shame her OP power and role in Sailor Moon essentially makes her unusable as a character only coming out as a last resort in very specific scenarios.
Uranus is the one who started the trend of lesbian team members and performs an absolute faultless performance in her role.
Neptune is Uranus' perfect partner, a textbook example of a princess style character done right, although I'd argue she's nothing without Uranus.
Pluto is forgettable, much like the planet itself and again her powers make her OP so she's only needed in very specific scenarios.
Chibi Usa - 4.3/10
Sailor Mercury - 8.7/10
Sailor Venus - 7.3/10
Sailor Moon - 7.5/10
Sailor Mars - 7.7/10
Sailor Jupiter - 9.7/10
Sailor Saturn - 8.2/10
Sailor Uranus - 10/10
Sailor Neptune - 8.6/10
Sailor Pluto - 6.3/10
