Honestly I really liked Thunderclan under Bluestar and under Firestar until he kinda started going a bit crazy. I grew up reading mainly about this clan. I had many of my favorite character in there because I was a basic elementary school student but even now that I'm nearly done with high school this clan will always hold a special place in my heart.
I loved Windclan in the first arc but the second Onestar took over I was so over it and Onestar as a character. He just became very obnoxious which to me really reflected on his clan. To this day it's definitely not one of my favorites.
