UIOP's one has more clauses.

those are the same ones. But the rest of the docstring introduces more of them:
recycle,mix,reexport…I have used
reexportwhich makes the following easier: you don't want to fullyusepackage A (for example, Alexandria). You want to import a couple symbols (easy, withimport-from), and you also want to export them (easy too, withexport). But in doing so, you had to write the symbols twice.reexportsaves duplication.I heard some complains that defpackage would fail to reload a package in some situations, and define-package worked fine, but I didn't encounter this situation.
(edit): another difference: let's say you ":use" a package in your
defpackagedefinition. Now you erase that line and you compile the package definition again. Your Lisp gives you a warning, telling that your package "also uses the following packages" and lists the one you removed from the definition. You removed the line, but the package still "uses" what you wanted to remove. You can check with(describe (find-package :my-package)).Do the same with UIOP's
define-package: you don't have warnings and your package doesn't "use" the one you removed from the definition anymore, as expected.
