I love Gladys. She's been a lovely villager. I've also had Blanche in my town since the beginning and I like her as well, though I oddly enjoy my other Snooty villager (Gloria, who I initially despised) quite a bit more.
I don't think there are any ostriches I love, but I don't dislike any of them. Many of them actually have really cool designs. Especially Flora the flamingo. I'd probably invite her, if she was at my campsite. I wish Julia was in NL. She looks so elegant and colourful.
EDIT: Also, I have a soft spot for Queenie. I had her as a starter in CF - hated her, because snooties were, well, really snooty. Then I got her in NL, and she won me over with her new personality. There isn't really anything special about Queenie, but because of our history, she became something special.
I really enjoyed having Phoebe in my town. I love most of them really, but they're not my favorites. The only one I'd invite into my town would probably be Flora.
I really like Queenie and Flora. Queenie is so pretty, I love her colors and the feathers on her head.
And Flora is just plain sweet. She has given me her picture three times now!
I'm considering Blanche to be my new Snooty as a replacement for Miranda.
I like Phil because he reminds me of Falco from Starfox.
Phoebe, imo, is of the few good looking Uchi characters (most Uchis are ugly to be honest).
