Ignoring the nonsensical media creation, boxing sucks for street fighting, (all kinds of boxing, using feets and hands, excluding muay thai that is pretty damn awesome).
Krav maga is completely popular in gyms and while it can be indeed effective, I would question how deadly it is and how effective it is for the average joe. A friend of mine that practiced it for years got his ass handed to him in a fight, when asked why didnt he answer properly he said that even though he positioned himself properly he couldnt react. Another friend of mine, a Tae-Kon-Do black belt, kicked plenty of ass in fights.
Muay thai, pretty much everyone I knew that practiced it hardly got its ass kicked. They often doubled with brazilian jiu jitsu and it helped.
Basically, think fast and be fit, and any martial art you practice will be useful.
Sambo isnt really popular in my country, but I sure as hell am interested.
Whatever you have on it, feel free to share.
