"UFC style fighting" is called Mixed Martial Arts (MMA). It's a training and competitive format where people usually train two or more martial arts side-by-side.
The most common martial arts used by MMA fighters are Wrestern wrestling (usually American folkstyle/collegiate, though Olympic styles like Freestyle and Greco-Roman are also used), Brazilian Jiujitsu, Muay Thai, and boxing, roughly in that order. Styles like Judo, Sambo, Catch wrestling, karate (usually full-contact styles like Kyokushin), and Taewkondo have also be used by top-tier fighter. There are also a few "MMA styles", or styles reflective of the MMA environment, like Shooto, Combat Submission Wrestling, and Combat Sambo. Occasionally, more unusual styles like Sumo and Capoeira have been part of a fighter's arsenal, but the first four are far and away the most common.
So what style is "best"? It's kind of in the air. An MMA fighter needs skills for distance fighting, clinch fighting, and ground fighter. To this end, we've seen, demonstrably, that full-contact training is more important than the label of the system. While fighters from certain backgrounds will have certain strengths- Judoka are great at throws and sweeps from the clinch, can keep their opponents pinned, and tend to be good at arm bars, while good Muay Thai practitioners, will generally have strong round kicks and maul guys with knee and elbow strikes in the clinch, for example- we've seen some unusual combinations work in MMA. It's about training for that environment. Boxing for MMA is different from boxing for boxing, BJJ for MMA is different from BJJ for BJJ, and the list goes on. The thing that boxing, Muay Thai, wrestling, and BJJ have in common is that they're all fairly wide-spread, all train for full-contact fights, and between the four of them, specialize in the most important aspects of MMA fighting- punching, low kicks and clinch striking, takedowns, and ground movement and submissions, respectively.
Combat sambo or shooto is the best bas style for mma as its a style in its own that has similar to amutaer mma and it the higher ranks of shooto has similar rules to the ufc the only difference in shooto is the gi is worn at at times cannot sambo is completely no go to my know which is only in shotto.
