I would plan on closer to 5 minutes. Both GC and ATT will have pretty consistent results. ATT doesn't mess with local pref for customer routes, so a simple pre-pend will cover you there. GC has quality SE's in my experience, so you'll know what to expect going in. I concur with Joe on Cogent, avoid at all costs.
