You don't want a tier 1 carrier as your ISP because they are severely limited in connectivity — they only connect to paying customers and other tier 1s. They are to be used as a last resort by the tier 2 ISPs, who provide good packet routing by selecting the best routes from among several backbones.
Never thought I'd see this play out in practice, especially with a consumer ISP. Normally this comes up with server hosting, not consumer ISPs.
