Each does have some differences. Akron has one set. Tallmadge, Mogadore, Cuyahoga Falls, Munroe Falls, and Stow are all very similar to rach other.
One example I can recall that is different is 42. For Akron, it is "half as dire" as 21 (officer needs help). For others, it is something else. I think it is Bank Escort for tallmadge, but it's been a while.
I agree, look at the lists on ScanOhio.com. They should be pretty close.
