Deciding between a partial DS3 and metro ethernet

We are in the process of upgrading the bandwidth at a few offices. Each currently have a 2xT-1 connection but have high utilization on the circuit which is why they are being upgraded. We are trying to decide b/t either a partial DS3 or metro ethernet connection. Are there pros/cons b/t the two in order to help decide which to go with? Cost is not an issue. Some say going with a partial DS3 circuit offers benefits over metro ethernet such as network-based failover, end-to-end availability is better with DS-3 and QoS.

Thx in advance for any advice provided.

I would choose metro-ethernet without any doubt.

It's a simpler, faster, more scalable technology that belongs century.

You can carry VLANS on it and it doesn't involve costly interfaces.

DS3 does not offer nothing of the above.

DS3 router interface cards are costly and may require a upgraded router platform.  Ethernet is the better choice.

I too would recommend the Ethernet hand-off, but whoever recommended DS3 might have confused the media with the devices using it.  Often only routers would support a DS3 serial interface, while any Ethernet device might connect to the Ethernet hand-off.  A common problem of the latter, Ethernet hand-offs for MAN or WAN might benefit from features not routinely found on typical LAN Ethernet devices.  As long as you use a device that can provide the features you need for your Ethernet hand-off, the latter is generally a better media choice.
