krav maga or MMA? which is best for me!?

So recently ive noticed when ive gone out to clubs that there seems to be more and more violence happening, also ive been travelling a lot and have found myself on occasion in some hairy situations where you ae clearly a target as an outsider to the locals. So I want to take up a form of martial art so should the time ever come im completely confident i can deal with what ever comes my way. I mean sure yeah i can brawl but im looking for something more technical that is going to end a fight before it really gets the chance to get going. I appreciate that MMA is more confrontational but sometimes the best defence is offense? any help or other recommendations would be great! thanks!
