Boxer/Out-fighter
Heavyweight champion Muhammad AliA classic "boxer" or stylist (also known as an "out-fighter") seeks to maintain distance between himself and his opponent, fighting with faster, longer range punches, most notably the jab, and gradually wearing his opponent down. Due to this reliance on weaker punches, out-fighters tend to win by point decisions rather than by knockout, though some out-fighters have notable knockout records. They are often regarded as the best boxing strategists due to their ability to control the pace of the fight and lead their opponent, methodically wearing him down and exhibiting more skill and finesse than a brawler[citation needed]. Out-fighters need reach, hand speed, reflexes, and footwork.
Boxer/Puncher
A boxer-puncher is a well-rounded boxer who is able to fight at close range with a combination of technique and power, often with the ability to knock opponents out with a combination and in some instances a single shot. Their movement and tactics are similar to that of an out-fighter (although they are generally not as mobile as an out-fighter), but instead of winning by decision, they tend to wear their opponents down using combinations and then move in to score the knockout. A boxer must be well rounded to be effective using this style.
Brawler/Slugger
A brawler is a fighter who generally lacks finesse and footwork in the ring, but makes up for it through sheer punching power. Many brawlers tend to lack mobility, preferring a less mobile, more stable platform and have difficulty pursuing fighters who are fast on their feet. They may also have a tendency to ignore combination punching in favour of continuous beat-downs with one hand and by throwing slower, more powerful single punches (such as hooks and uppercuts). Their slowness and predictable punching pattern (single punches with obvious leads) often leaves them open to counter punches, so successful brawlers must be able to absorb substantial amounts of punishment. A brawler's most important assets are power and chin (the ability to absorb punishment while remaining able to continue boxing).
Swarmers/In-fighter
In-fighters/swarmers (sometimes called "pressure fighters") attempt to stay close to an opponent, throwing intense flurries and combinations of hooks and uppercuts. A successful in-fighter often needs a good "chin" because swarming usually involves being hit with many jabs before they can maneuver inside where they are more effective. In-fighters operate best at close range because they are generally shorter and have less reach than their opponents and thus are more effective at a short distance where the longer arms of their opponents make punching awkward. However, several fighters tall for their division have been relatively adept at in-fighting as well as out-fighting. The essence of a swarmer is non-stop aggression. Many short in-fighters utilize their stature to their advantage, employing a bob-and-weave defense by bending at the waist to slip underneath or to the sides of incoming punches. Unlike blocking, causing an opponent to miss a punch disrupts his balance, permits forward movement past the opponent's extended arm and keeps the hands free to counter. Some in-fighters have been known for being notoriously hard to hit. The key to a swarmer is aggression, endurance, chin, and bobbing-and-weaving.
Counter puncher
Counter punchers are slippery in the pocket defensive style fighters. They use their well rounded defence to avoid or block shots. When their opponent throws a punch they use their defense to avoid blows and then they return one. They mostly fight at a close range; but some counter punchers remain at the distance of an out fighter. To be successful using this style he or she must have well rounded overall skills, a sharp boxing brain, and while blazing speed isn't always necessary, good speed at the least is required.
I'm a brawler/slugger. This is of course assuming it was strictly a boxing match, i know in a fight things get crazy and other styles/factors come into play. But as far as boxing goes, that's definately my style...
