Southwest Austin AISD elementary schools

We live in 78704 and will need to transfer our kindergartener to a better school than where we are zoned to. We are considering Zilker and Barton Hills in our zip code but know that transfer is not guaranteed there. So we are expanding our search south...
Would love to know what y'all think about the 4 elementary schools near Circle C: Clayton, Mills, Kiker, and Bear Creek. We will tour them in the next weeks but would appreciate more opinions from this community.

Vibes, culture, diversity, academic rigor, social emotional support, school libraries, PE, music and art, security, lunch, PTA, staff turnover, facilities...good and less than ideal, what do you like about them and what can be better. Please share!
