footwork

After doing research, I found that circular(kung fu) footwork is very effective in getting in and out while fighting. What specific martial arts or kung fu styles are best known for this. If i am wrong please let me know what styles are better.

Most kung fu styles offer circular attacks. Wing Chun is primarily linear, but is exception from the others. Ba Gua is probably the best circular form because it is internal. However, being an internal art means it takes a little longer to learn. Any school which teaches 5 animals will contain the circular skills you seek.

Western boxing and muay thai are also known for top grade footwork.
