This Precure does have a more interesting side to it. While the format of the plot is a big upgrade, the precures themselves are a mixed bag.

Megumi is very much the default precure protagonist and never really brings anything new to the table but makes up for it alot by being one of the most creative fighters in the franchise.
Hime has a story that makes her the real protagonist of this season as she was tricked into unleashing the bad guys and all plot points seem to lead from her and her development from incompetent to strong Precure along with her willingness to forgive Fortune makes her one of the strongest written characters in the franchise.
Yuko is described as a fluffy person who acts as a Precure backup to the various teams around the world, I give her points as she's the only magical girl who knows how to use a magic baton properly.
Iona on the other hand, her actions and personality make her the most out of character Precure in the whole franchise. Her toxic disdain for Hime was way over the line, she selfishly uses the other team members as her backup rather than as actual teammates, she's a hypocrite as she was more at fault for losing her sister to the enemy and even when she does forgive Hime and started being an actual Precure, she didn't really earn it.
Aino Megumi - Cure Lovely - 8.3/10
Shirayuki Hime - Cure Princess - 9.6/10
Omori Yuko - Cure Honey - 8.1/10

Best Dressed Award - Honorable mention to Hime but it's Cure Lovely that gets the best forms.
