Other than the huge difference of strict complaining, the differences are almost non-existent. But not totally so, as the following code sample shows: 
sub foo {print "world,\n"}

my $func_name = "foo";
my $func_ref = \&foo;

# Replace foo
*foo = sub {print "Hello "};

&$func_name();
$func_ref->();
