Really?  That surprises me; people complain about Cogent on here, roughly,
weekly.  :-)

The implication of everyone's "in a BGP mix" responses, in case you don't
get it (and I suspect you might not) is that you don't want Cogent to be
your *only* upstream provider.

If you're going to resell the bandwidth as an ISP, best practice says you
should have at least 2 upstreams.  3 or more is better,

Cogent has had a bad habit the last 5 or 10 years of getting into pissing
matches with other carriers about peering, and just cutting them off
(or being cut off)... which of course means that if they're your only 
connection to the Internet, then your customers simply can't reach sites 
connected to those providers.

So, in short: no matter how agressive they are, they're not the carrier
to have when you're having only one.
