Many characters have high end accuracy feats, but that's just it: they're high end showings.
Bullseye does those same things in his baseline appearances. Flicking a toothpick through window glass to snipe some lady is day to day stuff for him. It'd be an ultra high end respect thread feat for 97% of other characters.
I think Deadshot can match in some ways, but I'd have to side with Bullseye overall.
How are you going to look at Bullseye killing someone with a toothpick, factor it in and then say "But could he do it with a gun at a longer range when he has much more control and bullet ballistics that's common knowledge available to him? Thought so!" You'd be lucky to throw a toothpick within 2 feet of your target in your room with minimal air resistance or winds, let alone calculate it going hundreds of feet with a flick outside through a window at killing velocities.
