Might be kinda of a non-issue at this point--but are the choices you have listed the one you have
AVALIABLE or are they just the ones you
WANT to look at?
The reason I ask is that the one
"which provides the most real world self defense benefit" is generally the one you, yourself are best at.
Nor are all gyms/dojo/dojang/kwoons/etc. the same. MMA style training is good but not if the only gym in your location kinda sucks.
You should probably take into consideration that "other" factors are just as important as "style" when it comes to training. Stuff like:
-Is the teacher any good? They might be real tough people but can they TEACH what they know?
-Can you make the classes you want--some places have good training and teaching but not at the times you have avaliable.
-Can you afford the classes--hate to get all real-world in you, but these days costs--gas, class cost, opportunity cost etc. sometimes makes a real difference.
-What are your training buddies like? Most of what you list you kinda/often need a partner to work with. Are such people avalaible for you at the time you wish to train?
-What is the background of the people teaching---you are getting ready to join a "gym" that offers:
-K1
-Kickboxing
-Muay Thai
-Boxing
-Brazilian JJ
-MMA
A-Some gym
B-Is the same person teaching a couple of these or do they have 6 different teachers?
You probably have already thought about all these--just mentioning it.
