As well as regional differences (in both the U.S. and the U.K.), some of the things are purely subjective anyway, for example:
Cons to the US
1. alot of my family and friends live in small towns
That's a con if you like big cities, a pro for those of us who much prefer the small-town atmosphere (in either country).
3. where I lived public transportation was a joke
Again, regional differences. Public transportation in rural Norfolk is a joke too.
16. council taxes that you can see the benefit of
Where's that? In the last 10 years council tax in my area has more than doubled, yet the services have deteriorated. This has been happening all over the country.
2. You can carry protection (no not a gun)
17. "right to bear arms"
Isn't listing one of those as a pro and the other a con kind of contradictory?
Cons of the Uk
4. you cannot carry mace
In theory you can. The Bill of Rights says so. The Prevention of Crime Act 1953 says so. It's just government and police "policy" which will get you into trouble for doing so.
