That's sort of a loaded question. Some provider's offerings are good for different reasons/have different strengths. Your best fit would depend on your individual needs. How many sites will you have, and what is your access method and speed preference? Do you need granular QoS from CPE to CPE or will queuing on the access loop suffice? Prefer or require layer 2 (Martini, Kompella/Lasserre, etc.) MPLS vs. layer 3 (2547)? Do you need the service to support multicast? Does your WAN require the service to support an IGP (OSPF, RIPv2, etc.)? Do you require internet access over the same access loop? Require the provider's network to be physically separate from the public internet? Plus many more... The answers to these questions should significantly narrow your choices.

Does anyone have personal experiences they'd care to share about providers...the good, the bad, the ugly? I'm not looking for public bashing, just data to differentiate one from another. Any comments or direction appreciated. Andrew
