If a packed Javascript saves 20kb off the download size, but takes a perfomance hit to unpack, then are there any benefits, besides obfuscating the code?

Packed javascript code generally does not take longer to execute vs regular code. Most code packers will shorten variables, function names and use a host of tricks to make the source smaller. The resulting source is fully executable! You can verify this by taking a look at it during runtime with firebug. You’ll see the compressed code executing in its minimized form.
