[DC] Considering Bruce Wayne recovered from his broken back relatively quickly, why did it take so long for Barbara Gordon to recover?

His back wasn't completely broken.  He still had limited use of his legs. He also had a doctor with powers that she used to accelerate his healing, but he was still on the way to recovery without that.

Barbara's spinal cord was completely severed.  She never recovered in old continuity and when the N52 reboot happened, it was experimental surgery that allowed her to recover.  Surgery that wasn't available until 3 years after she was shot.
