Eh, she's ok. I had her as my normal starter in my first ever GC town and loved her so much I named my alt character Kiki. She later moved to one of my other towns which I visited the other day, she still lives there today after 10+ years, and it's the same one! My snooty starter from my first town was Olivia, and she STILL lives in that first town, same plot right next to the area where the player characters live
I never had her in WW or CF, but I remember at first I wanted her. After a little while of playing WW, though, I developed some new favorites and forgot about her. I still enjoyed seeing her from time to time in the City from CF.
In NL, I still kind of wanted her but not enough to go trading or anything. In my first town she moved in when I had gotten bored and I think I only played maybe three or four times after she had moved in before I reset. Her charm was kind of gone tbh.
In my new town I honestly haven't thought twice about her. Except once. I was campsite resetting to get a new villager I liked (I didn't have anyone in mind, just someone cool I guess) and after maybe four times I saw her. For a split second I hesitated and thought about choosing her to move in. Then I turned off my 3DS and continued with the campsite resetting process.
However, I have her amiibo card and my mom is moving her in after she scans the Goldie and Purrl cards. My mom shared that GC town with me and loved Kiki so much and never forgot about her. We both loved her so much and pampered her with gifts and favors, she was like our town's little princess
