Which martial art do you recommend for me?

I love all martial arts but I want one perfect for me. I really like grappling and a little striking as I think this combination would be the best for self defense. What do you think?
Which martial art can be used easily and applicably for self defense Judo, JuJitsu or Aikido.
I would love to defend against knives guns and also kicks and punches. I would like to end a fight quickly as I live in a rough area of town and I am still very street wise though. What can throw a person with minimal effort and end a fight quickly as well as be a little bit peaceful, AKD,JDO OR JJTSU? I like throws and take downs, locks, submissions and strikes but mostly the first two. So what do you reckon is the way to go? Leave your comments, suggestions and opinions below Thanks :)
