Desktop is also no strings attached, it includes free Neo4j Enterprise Developer licences and is just a much better experience than the old crappy installer.
It also allows you to create multiple graphs for different projects, install apoc, graph-algos and graphql with a button click and also install (and develop) graph apps, e.g. for monitoring, modeling etc.

You cannot install desktop on top of a server install (community or enterprise) but you can copy your graph data over.
