I reckon ive had a good go at most of em, being REALLY into it as a kid and often going 3 nights a week to various martial arts disciplines during high school and have the following things to say based on my limited eperience (as i am well aware there are those out there who have had decades more experience than i)
(pardon the spelling)
Aikeedo, frustrated the hell outta me but very zenn if you do it right. is all about chi and balance. quite a dangerous martial art once you become proficient, which i did not after a year
Judo, fantastic and one of my favourites, very much about using your opponents force against him/her and a great grappling martial art. did this for a number of years and still dont believe i am incredibly "good at it"
Karate, i only did this for a year and found it was mostly blocks and a couple of uniform punches and kicks and didnt really enjoy it at all.. sparring was boring as all hell. This was my youngest martial art (started when i was like 7) so it was probably mostly just my attention span.. obviously didnt get that good.
Kickboxing, mixture of a combination of styles to what i like to call "bastard style" which included some mui thai but mostly american, was fantastic to mix it up and had a heap of fun competing. really good for exercise (obvious i havnt been doing it for a while based on the gut) and is the best for a more fun and energetic martial art, did this one for years and found i use a lot of the principles from this martial art in my work, as well as the principles learned from judo and jujitsu aswell (i am occasionally required to subdue violent people in my line of work, usually words work, but occasionally they do not)
Jujitsu - fun as, but teacher went bust so only did it for 1 year, would have loved to do more
Roman grecko - boring and slightly erotic (too much so), makes you realise the importance of your legs in ground work. only did this for 3 months, once you have the basic principles down pat and if you have legs the size of mine, you can get pretty alright pretty quickly.
All these martial arts teach you that words are your best self defence and 9/10 times you will not have to fight anyone if you use the right words.
Every martial art i ever did, no matter how long i did it for, i never felt particularly good at any, because all of them had people doing it for over 20 years who would put you on your *** by looking at you. These people are here to remind you that nomatter how good you think you are, theres still plenty of training to do
