Hi,

The basic difference between L-2 and L-3 EtherChannel is that an L-3 EtherChannel has all the feastures that are available to an L-3 interface. Though it doesn't offer much help in pure LAN Switching environment, however the benefits are higher when one is combining Routing with the LAN Switching environment i.e. you may include Routing Parameters to engineer traffic patterns or you may include L-3 based ACL or even Network Manangement Features for the logical interface.

HTH
