What in your opinion is the best martial art for kicking?

i want to do a standup ma that focuses on kicks but i dont know what ma would be the best. i know tkd is heavy on the kicks but i know tkd has a bad reputation for birthing mcdojos that focus on kicks that wont work in real life. would i be better off taking kickboxing or muaythai, or is there an othe ma that focuses mainly on kicks
