as for Hawkeye being a copy of Green arrow its not really true.
Ollie is more a copy of batman than hawkeye is of ollie, hawkeye is more like a spy while green arrow is a classic swashbuckler hero.
Ollie is shown to do parkour in a way similar (but not as good) as to how Cap did it in avengers movie. and he more frequently avoid gunfire (plus he has the one clear arrow dodge in his fight with merlyn)
He has superior mobility and IMO superior speed.
his training speeds show he has decent strength, although he has no high end strength feats yet but neither does hawkeye.
hawkeye does better no look shots, ollie hits multiple moving targets without difficulty. Hawkeye curved an arrow around a hellcarrier using the wind. Ollie hasnt done anything near that level.
Ollie has an explosive arrow that seems a bit stronger than a hand grenade, while hawkeyes seems to blow up a small building.
Ollie however has experience fighting another archer and hawkeye does not.
