For a month or so, I had both HawaiianTel and Oceanic cable in my house. Extremely similar plans and prices. For my neighborhood (Kaikuki) at the time, Oceanic kicked HawaiianTel's ass. Oceanic consistently delivered between 85% - 200% of the bandwidth I was paying for, while HawaiianTel consistendly delivered <40%. I called their tech support. After three different phone sessions, each of which failed to resolve the issue, they said "Ok, we will just leave your service request open." No promise to resolve it, no offer to send a technician.
Since then, HawaiianTel has put new fiber optics in my 'hood, and tried to recruit me on that basis. Still, they are not offering anything Oceanic isn't, and they pissed me off with their lack of service.
