This rank is the hardest to do.

Having to follow Heartcatch would give anyone cold feet and Suite did it's best but it was no where near the same quality, that kind of reflects in the Cures.
Hibiki were back to the bright and full of energy pink cures, she's not bad per say but she's an awkward cross between Dream and Aqua, melding into a very botched character as it's difficult to play her as the lonely rich girl.
Kanade is very difficult to like as her bog standard girly personality doesn't mix well with some of her weaker traits such as stubbornness and for someone who's meant to be a second half to a duo, she's horribly underused as a Precure and causes the team to fall apart.
Ellen saves the team by having a good backstory, she starts as a fairy cat who gets manipulated into joining the bad guys and then after becoming permanently human gains precure powers, making her personality changes more believable, not to mention she's a great strategist and she can use her hair as a guitar, that's awesome.
Ako is a brat but with good reason having been forced into becoming a fleeing princess aged 9-10 and trying to act mature to save the Kingdom, so her rudeness is justified when other characters treat her like a kid. Plus her masked form is a homage to Doronjo
