And in terms of working and living abroad, a British passport gives you the automatic right to live and work in 28 countries (EU + Iceland, Switzerland and Norway) + probably a few Commonwealth countries, whereas a US passport gives you the automatic right to live and work in ... 1 country. Seems an easy choice to me!
I suppose Americans have their 50 states (your "1 country") plus a few territories (Guam, Saipan, etc) to work in and Europeans have their 25 countries (the size of US states) plus a few other States.
As for easy access to countries, I have worked and traveled to many countries in CEER, EMEA, FSU, Africa, Asia, etc that have no issues with US Passport holders walking in without a visa, or allowing an instant visa issuance. In fact, EU and US passports are roughly on par as far as access to States.
As mentioned above earlier, I have rights to an EU passport but never needed to get one (even despite living in Europe for 4.5 years) as my US Passport has been quite adequate.
Not that one is better than another...and that's my point.
