What is the best.............?

hey guys i was trained in karate when i was about 8 or something & later i stopped & i continued it again with a few extra classes too and again b'coz of my studies i had to stop it so now i desperately want to continue it.Hence i wanted to now should i continue in karate or should i go for judo or any other form of art. (I think u should know, i have completed till purple belt). I can put any amount of effort just tell me which is the best. Also just let me know if they are any coaching classes in delhi which trains girls only or both girls and boys.
