•          Supports J2EE 1.2, 1.3 and 1.4 specifications

–        Can upgrade runtime environment without upgrading applications

–          Supports mixed version nodes in a v6 ND Cell

–        Allow for migration in stages within a cell

–        Mixed v5 and v6 nodes must have v6 DMgr (can’t add new v5 node)

–        v6 ND introduces profiles

–        Each profile has its own user data including WebSphere configuration

–        All profiles share same WebSphere binaries

–        Less disk space required than separate installations

–        stand-alone server, deployment manager or custom profile

Quick answer is besides the JDK 1.4.2 from 1.3, 5x has WsInstance implemenation for multiple servers whereas 6x implements profiles that are better manageable and maintainable.
5x only creates separate configuration of the JVM but else everything is shared between server instances.
On 6x each profile can be managed independently without affecting the others. This helps in running different versions of you app in the same environment. So you could have a Dev, QA and Stage environment in the same server.
6x provides a distinct separation between product binary files and all instances of user data, all of which is encapsulated in one or more profiles
Deployment tool in 5x is replaced by PCTool (Profile Config tool)

Hope this helps.
