We have had Cogent over Verizon's Fiber for more than a few years now. 
Cogent goes down once at year at minimum. They had 2 outages in a single 
day a couple days ago in Northern NJ.  One in the AM "..caused by a 
power outage in a vendor data center where Cogent is collocated." They 
went on to have another outage at around 9:30 PM on the same day for 
which I'm still waiting for an RFO. During this outage, they still were 
advertising our BGP routes so we didn't fail over to our 2nd provider. I 
notice that happens alot with them. When they go down, they still 
advertise your routes.

As far as price goes, for us Cogent is cheap but Lightpath is cheaper.

Our college is kind of far from things so we don't have a lot of outside 
fiber coming. The last mile fiber for both of our connections are 
different from our Internet providers. I've never had a big issue with 
the two working with each other. The only issue we had is I suspected we 
weren't getting as much bandwidth as we paid for. They had to work out 
where the policer and/or bottle neck was. This is the only issue we had 
in 5 years with this set up and it got resolved. IME, when there is a 
full outage, it's always been clear who the responsible party is.
