Some of those providers are probably not in the DFZ.  I know Cogent has 
been involved in some peering spats in the past.  I don't know off-hand if 
Zayo/Above lives in the DFZ.

Mainly customer service.  Things like how easy it is to get a clued 
individual on the phone when there's an issue, turnaround time for things 
like BGP filter update requests.  Like you mentioned, most providers' SLA 
terms are likely to look pretty similar if you were to compare them 
side-by-side.

I would also look at which providers are on-net in your location, or would 
be willing to build into your location for a reasonable cost.  One thing 
you want to avoid is all of your providers using the same local loop 
provider to get into the building, or local dark fiber providers using 
the same right-of-way / conduit / manhole to get into your building.
Many providers might subcontract the physical last-mile construction to a 
local dark fiber provider.  Entrance diversity and last-mile diversity is 
something you can probably have more influence over than how provider X 
gets between Chicago and New York.

Many providers will build into your location if they're in your city if 
you either pay the build costs, or are purchasing enough service that the 
construction costs can amortized over the term of the contract.  If they 
amortize, make sure you keep that in mind when the contract is up for 
re-negotiation, so they're no longer trying to ding you for construction 
costs that you've already paid :)
