Answering your question in the title, not your real question (which Corion already answered accurately):

There's another difference which the documentation is silent about, and that's the version of the module: 

$ perl -wle 'use CGI 100'
CGI version 100 required--this is only version 3.15 at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

$ perl -wle 'BEGIN { require CGI; CGI->import(100) };'
# (no output)

From the documentation there's no obvious way to require a minimal version of a module (expect checking it manually, and die if it's not large enough).
