A study was recently published and I'm not too surprised at how NYC ranks:
The study is here:

In terms of the continent, were 1st, but other rankings are lower: the lower the ranking, the worse the score
Commute time: 22 out of 23 (Summer of Hell, anyone?)
Economic opportunity: 9 out of 23 (I disagree with this)
Public finance: 21 out of 23 (with $40 billion in debt, a gold-digging guv 'nor, and a stubborn resistance by the mayor to MoveNY plan, how else?)
Road network efficiency: 23 out of 23 (sorry, Moses - you tried)
Affordability: 15 out of 23 (with fares 27% higher than nat'l inflation and 50% higher than surrounding agencies, this will only get worse)
Utilization: 5 out of 23 (managing delays has gotten better, but the MTA should really consider the Triboro Rail, largely disused by revenue trains but reliable for cargo transport)
