Azumanga Daioh, Sasameki Koto Recommendations
Comedy around high school girls. Though Sasameki koto has some yuri & romance parts leading to slightly heavy moments, the series is 80% funny and highly enjoyable.
Both series got good pace, arrangement and scripts.
Slice of life stories about 6 high schoolers.. the most similar characters would be Sumika and Sakaki for being the tallest, and most athletic.
