The main differences are related to the Martini and Kompella method of implementing the technology. For example l2vpn is based on MBGP with RSVP doing the LSP signaling and advertising the labels. This means that the path of the circuit is handled as if it were a virtual circuit because RSVP signals and reserves the bandwidth before traffic is passed. l2circuit is based on LDP which sends hellos end to end but depends on the IGP for resource reservations. The data forwarding is technically the same and you can achieve the same results with either though. Personally, I'm a fan of l2vpn the use of RSVP allows for more tidy configuration and bandwidth reservations. I think l2vpn is a little easier to troubleshoot as well, however YMMV.
