I have both gameplay and characterizations in mind for my ratings.
>stage 1
Rika
I played the mainline Touhou games in release order, so I have some nostalgia for TH2. I'm especially fond of her stage's music, and she has some funny banter with Reimu.
>stage 2
Parsee
Her fight is fun, both her stage and her boss fight have good music, and I like her design a lot. Her habit of getting off on misery makes me want to give her a big hug, knowing full well she'll probably rip my spine out for doing so.
>stage 3
Alice
She's my favorite Touhou character, and both TH5 and TH7 are among my favorite Touhou games. Her design is amazing and all of her themes are great. Her aloof and haughty characterization makes for good banter with other characters, especially with Marisa. It's such a shame ZUN stopped using her, and I hate that there are doujin authors who treat her as little more than the butt of their cruelest jokes.
>stage 4
Satori
One of my favorite characters from one of my favorite Touhou games. Her fight is fun, her stage and boss themes are great, and she's very cute. 11/10.
>stage 5
Mima
TH2 was the first Touhou game I got a 1cc on, and Mima immediately made a strong impression on me with her awesome music and how much practice I had to put in to beat her third phase which was immensely satisfying to do. She had a strong presence in TH3 and TH5 as well, and she's uniquely the only other character from TH1 to make reappearances in later games alongside Reimu. All of this makes her abrupt disappearance in the Windows games especially jarring to me, like one of the main characters just vanished without so much as a passing mention.
>stage 6
Yuuka
My second-favorite Touhou character. Her design is great and I like all of the games she plays a role in. It's always fun to see her threaten her opponents with extreme violence, even if she just says shit to get a rise out of them. It sucks that ZUN shelved her as well, going so far as to consider her a "guest character" even though he made her.
>stage EX
Flandre
She's the only extra stage boss I've beaten, so she's here by walkover. Even with that in mind, she has a pretty fun fight and everyone loves U.N. Owen Was Her, myself included. I haven't read CDS nor have I played TH17.5, so I have no idea what her characterization is beyond being a naive shut-in.
