I wonder if it might not have something to do with being "on" all the time vs. appearing only one night a year with a discrete purpose.
Mary was always there trying to protect and only had enough oomph to destroy the poltergeist by eating up her own essence or whatever. I think the boys showing up freed her to do that, or she would have not taken it on knowing it would destroy her.
Roadkill girl (Molly?) didn't even know she was dead. She appeared full on and solid one night a year trying to find her husband, so all her power as a ghost was saved up for a discrete event that happened annually.
I think it's probably harder on a ghost to be in Mary's position. Probably dissipates their power somewhat.

That's my theory, anyway.
