Although you already made your choice I still want to put in a few words for in case other people have the same/similar question.
First of all let me start by saying there is no 'best' martial art.
All martial arts have their pro's and con's.
You must question yourself, what kind of person am I?
- Quiet, to myself
- Outspoken, energetic
- Manically depressed
- stressed out
- Overly relaxed
- athletic
- as athletic as a piece of steel?
Once you defined your character you need to ask yourself, what do I need?
- Boost confidence
- Become more athletic
- Keep to myself
- Relax and tone down my energy?
- get more energy
The you have to look at the different martial arts and think what they would do for you.
- Aikido needs you to be calm and relaxed, you anticipate and react on events, take over control. It's more soft then hard
- Karate boosts your energy and make you pro-reactive, strike first of get hurt, your goal is to prevent. Be quick, fast and hard.
- Judo is people who like to hug eachother.
- Jiu jitsu is a combination of all of the above.
- Tae Kwondo, Wing chun, kung fu, pentjak silat, Krav Maga, Tan sa do are all similar to the idea of karate.
I myself have done Aikido, judo, Tan sa do, Jiu jitsu and kyokishin karate. In retrospect I would say that aikido is my kind of martial art. It's peaceful and yet let's you obtain control in a fight. Once I have control, the fight is over.
You will see that once you make these analyses you will instinctively know which martial art is best for you.
Peace
