Bullseye - In any accuracy discussion, his name always comes up. He's good at taking anything and throwing it with pinpoint accuracy, and can even turn ordinary playing cards into lethal weapons. He isn't the first one to be considered a super marksman since he was only introduced in 1976, but he's the only one who does it with his level of efficiency and versatility.
The way he uses his ability, it's as if he has power over the mass of an object and the velocity at which they leave his person. How can one possibly spit a tooth through someone's skull. At most, that would only cause disgust and annoyance, but Bullseye can do it, apparently.
Hawkeye - Clint Barton was once known as a one-trick pony, but he's proven time and time again that he's all about accuracy. After Captain America's apparent death, Stark couldn't find anyone to wield the shield until he gave it to Hawkeye, who was able to use the shield perfectly stating "It's all about accuracy." That proves that he's not only good with a bow, but with other ranged weapons as well.
He does have other skills like his fighting ability and mastery of other martial arts weapons, but that's not what we're here to talk about.
Ultimate Hawkeye, on the other hand, is a totally different animal. Think Grifter + Bullseye. For our purposes, though, let's stick with 616 Hawkeye.
Longshot - The Mojoverse slave race guy has a peculiar set of powers. He isn't particularly touted as a guy with superhuman accuracy, though he does sling those knives of his with extreme precision. Some people say it's his luck aura that makes him a fantastic marksman, but in a very recent issue of X-Factor, Tier (Rahne's son) says that no one really believes that Longshot uses his luck to throw his knives.
Deadshot - Floyd Lawton is an assassin who claims to never miss, which he has proven over and over. The New 52 Deadshot is sort of like the old Deadshot, but is a little bit more of a bad ass. While he normally uses his wrist-mounted guns, which I assume are horrible for his bones, Deadshot is also a master of any firearm. Out of the ones in we've listed, he's probably the most accurate at the longest range.
Green Arrow - While I absolutely loved Old 52 Ollie, I'm eventually going to have to accept that he's gone and has been replaced with Generic Arrow. GA now is still as accurate, though. He's still considered the premiere archer of the DC Universe. He's done some crazy stuff like shooting an arrow down a barrel of a gun or splitting a water droplet. What I can say against him is that he isn't as versatile as Hawkeye or Bullseye, having trained specifically with the bow and arrow.
If these guys were put in a show like Top Shot, who would you pick to win?

If not these guys, who else do you think deserves to be part of this list? I can hear fanboys cry out "BATMAN!"
