What is a better method of testing, circuit based access such as OC48 or a carrier ethernet access?

Re: circuit based access or carrier ethernet access? 
Carrier ethernet provides access to the internet with native Ethernet packets, as opposed to circuit based access methods as T1, T3, OC3, OC48 etc. An advantage of being packet based is that carrier Ethernet services can support Class of Service (CoS). Carrier Ethernet also supports true multipoint communications. Older WAN technologies as ATM and frame relay offer point-to-point connectivity only. Although Metro Ethernet is often thought to be analogous to Transparent LAN Services, Ethernet can be used as a broadband access technology to point-to-point Layer 2 VPN, Layer 3 VPN, and Internet services.
